Docs: Simplify getting started docs

It is no longer necessary to check out a version of `github/codeql` as
a sibling directory to the distribution. Instead, users can download
the required packs as needed. using the `pack download` command or
the `--download` option for `codeql database analyze`.

is unchecked.
2. Create a new CodeQL directory
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Create a new directory where you can place the CLI and any queries and libraries
you want to use. For example, ``$HOME/codeql-home``.
The CLI's built-in search operations automatically look in all of its sibling
directories for the files used in database creation and analysis. Keeping these
components in their own directory prevents the CLI searching unrelated sibling
directories while ensuring all files are available without specifying any
further options on the command line.
.. _local-copy-codeql-queries:
3. Obtain a local copy of the CodeQL queries
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The `CodeQL repository <https://github.com/github/codeql>`__ contains
the queries and libraries required for CodeQL analysis of C/C++, C#, Java,
JavaScript/TypeScript, Python, and Ruby.
Clone a copy of this repository into ``codeql-home``.
By default, the root of the cloned repository will be called ``codeql``.
Rename this folder ``codeql-repo`` to avoid conflicting with the CodeQL
CLI that you will extract in step 4. If you use git on the command line, you can
clone and rename the repository in a single step by running
``git clone git@github.com:github/codeql.git codeql-repo`` in the ``codeql-home`` folder.
The CodeQL libraries and queries for Go analysis live in the `CodeQL for Go
repository <https://github.com/github/codeql-go/>`__. Clone a copy of this
repository into ``codeql-home``.
The cloned repositories should have a sibling relationship.
For example, if the root of the cloned CodeQL repository is
``$HOME/codeql-home/codeql-repo``, then the root of the cloned CodeQL for Go
repository should be ``$HOME/codeql-home/codeql-go``.
Within these repositories, the queries and libraries are organized into QL
packs. Along with the queries themselves, QL packs contain important metadata
that tells the CodeQL CLI how to process the query files. For more information,
see ":doc:`About QL packs <about-ql-packs>`."
.. pull-quote:: Important
There are different versions of the CodeQL queries available for different
users. Check out the correct version for your use case:
- For the queries used on `LGTM.com <https://lgtm.com>`__, check out the
``lgtm.com`` branch. You should use this branch for databases you've built
using the CodeQL CLI, fetched from code scanning on GitHub, or recently downloaded from LGTM.com.
The queries on the ``lgtm.com`` branch are more likely to be compatible
with the ``latest`` CLI, so you'll be less likely to have to upgrade
newly-created databases than if you use the ``main`` branch. Older databases
may need to be upgraded before you can analyze them.
- For the most up to date CodeQL queries, check out the ``main`` branch.
This branch represents the very latest version of CodeQL's analysis. Even
databases created using the most recent version of the CLI may have to be
upgraded before you can analyze them. For more information, see
":doc:`Upgrading CodeQL databases <upgrading-codeql-databases>`."
- For the queries used in a particular LGTM Enterprise release, check out the
branch tagged with the relevant release number. For example, the branch
tagged ``v1.27.0`` corresponds to LGTM Enterprise 1.27. You must use this
version if you want to upload data to LGTM Enterprise. For further
information, see `Preparing CodeQL databases to upload to LGTM

``$HOME/codeql-home/codeql-repo``, then extract the CLI into
