* {@link ML_POWERED_JS_QUERIES_PACK.version}. If the version string

* "latest", however this shouldn't occur in practice (see comment below).
* - "false" if the analysis won't run any ML-powered JS queries.
* - "other" in all other cases.
*
* Our goal of the status report here is to allow us to compare the occurrence of timeouts and other
* errors with ML-powered queries turned on and off. We also want to be able to compare minor
* version bumps caused by us bumping the version range of `ML_POWERED_JS_QUERIES_PACK` in a new
* version of the CodeQL Action. For instance, we might want to compare the `~0.1.0` and `~0.0.2`
* version strings.
*
* We restrict the set of strings we report here by excluding other version strings and combinations
* of version strings. We do this to limit the cardinality of the ML-powered JS queries status
* report field, since some platforms that ingest this status report bill based on the cardinality
* of its fields.
*
* This function lives here rather than in `init-action.ts` so it's easier to test, since tests for
* `init-action.ts` would each need to live in their own file. See `analyze-action-env.ts` for an
* explanation as to why this is.
