ci: move every codeql-action pin to v4.37.9 in one commit

init, analyze and upload-sarif are the same release pinned in three
workflows. Dependabot opened them as three separate pull requests, so each
run mixed two versions and analyze rejected the config init had written:
"Loaded a configuration file for version 4.37.7, but running version
4.37.9". None of the three could go green alone, and the code-scanning
analysis stayed red while they waited on each other.

Bump all five references together and group the action in dependabot.yml so
the next release arrives as one pull request.
