Unpin codeql actions (jaegertracing#5787)

## Which problem is this PR solving?
- Renovate bot does not upgrade these because the main branch there is
on v2
- Code scanning does not need to be locked down as strictly as
reproducible builds

## Description of the changes
- Use v3 instead of exact commit or exact semver
- The logs still show the exact version used, e.g.
`CODEQL_ACTION_VERSION: 3.25.15`

## How was this change tested?
- CI
