chore: skip golangci-lint patch version renovate upgrades

golangci-lint cannot use truncated versions because pre-commit `rev`
versions don't match.

This reverts the truncated versions change for this dependency, and
switches to a strategy of ignoring patch versions.

This is a reasonable approach for golangci-lint as patch version
upgrades generally only cover dependency upgrades and minor issues, and
don't require Renovate MRs. In the case of a bug affecting the team, a
manual upgrade can be done. This is likely to be a a rare event, so on
balance will reduce workload for the team as much as truncated versions
would.

+1. If the dependency is used for `pre-commit`, the `pre-commit` `rev:` revision (normally a tag in the repo) must match

 1. Truncated versions only works with `mise`, since `asdf` does not support truncated versions.
 1. Truncated versions should be avoided for runtime dependencies, where having greater control over the providence
    of the produced artifacts is more important.
