feat(api): add tag_filter query parameter to release list API (#38681)

Adds a `tag_filter` query parameter to `GET /repos/{owner}/{repo}/releases` that filters releases by tag name, with `*` as a wildcard (e.g. `v1*`, `*beta`, `*rc*`). Matching is
case-insensitive and done in the database query. Literal `%`, `_` and `\` in the filter are escaped.
