fixed, diff-informed mode is disabled for these queries.

aabbfce010 Actions: Exclude model-generator queries from query suites
This change removes the model generator queries for Actions
sources/sinks/summaries from being run as part of the
`actions-security-and-quality.qls` query suite,
where they were accidentally included.

All languages will now exclude both `modelgenerator`
and `model-generator` tagged queries from their suites.

8808f0f824 Misc: Add script for calculating MRVA totals
Use this script if you want to quickly calculate the totals of some
query across all the queries in a MRVA run.

For an example of such a query, see e.g.
`python/ql/src/Metrics/Internal/TypeAnnotations.ql`

The script expects the query to produce an output table of the form
```
| header0  | header1  | header2  | header3  | ...
|----------|----------|----------|----------|----
| message1 | value11  | value12  | value13  | ...
| message2 | value21  | value22  | value23  | ...
...
```
where all of the `values` are numbers. For each `(message, header)`
pair, it then calculates the total of all the values in that cell,
across all of the repos in the MRVA run.

To use the script, simply pass it the URL of the exported Gist of the
MRVA run. After calculating the totals, the script will then
(optionally, but by default) add the totals to the `_summary.md` file,
and push these changes to the Gist.

## 4.3.0
### New Features
* New classes `TypeofType`, `TypeofExprType`, and `TypeofTypeType` were introduced, which represent the C23 `typeof` and `typeof_unqual` operators. The `TypeofExprType` class represents the variant taking an expression as its argument. The `TypeofTypeType` class represents the variant taking a type as its argument.
* A new class `IntrinsicTransformedType` was introduced, which represents the type transforming intrinsics supported by clang, gcc, and MSVC.
* Introduced `hasDesignator()` predicates to distinguish between designated and positional initializations for both struct/union fields and array elements.
* Added the `isVla()` predicate to the `ArrayType` class. This allows queries to identify variable-length arrays (VLAs).
