Fixes: #33735

Correct runner type selection for the lint job.

This was erroneously left-out during refactor of the runner selection mechanism in #33302 causing the lint job to run on GH hosts (and therefore not be able to acces local cirrus caches).

This is now selecting the correct provider.

Some follow-up ideas:

I ran codex -c model=gpt-5-mini --dangerously-bypass-approvals-and-sandbox exec 'Review the top commit' on ff18b6bbaf322739fe98fd51b0d89d65a5775ab5 for fun, and it printed:
```
**Potential issue I found**
- In `action.yml` the `cache-provider` `options` list contains `gh`:
  - `.github/actions/configure-docker/action.yml:4`
  - But the workflow sets `provider=gha` in `ci.yml` (`echo "provider=gha" >> "$GITHUB_OUTPUT"`).
```
Which looks real. I guess given that GitHub seems to ignore if wrong options are passed and doesn't do any validation anyway, it seems fine to remove them?

Also, could use a yaml anchor to re-use the snippet and specify the runners verbosely for the lint as well:
```
            cirrus-runner: 'ghcr.io/cirruslabs/ubuntu-runner-amd64:24.04-xs'
            fallback-runner: 'ubuntu-24.04'
```
But those are just nits. Feel free to ignore them.

I think it would make sense to include here.

ci: fix configure docker action inputs

The options used were wrong in two ways: firstly they were not enforced
as a "choice" (i.e. invalid input valudes could be provided without
error) and one of the options was listed as `gh` when we passed it as
`gha` from ci.yml.

"Fix" this by removing the choice altogether but sanity-testing the
input value against an expected list using a GHA "warning" to notify of
unknown inputs.

Sorry for the slow turnaround.

I pushed an additional commit to address (half of) @maflcko's nits. He is correct that GHA apparently does not validate inputs (even if you set type: choice), so it makes sense to remove the options. In order that we not miss if the wrong option is passed here in the future I added a sanity check which will annotate the CI run with a Warning when an unknown input is detected. See the bottom of the annotations of this run for what that looks like: https://github.com/willcl-ark/bitcoin/actions/runs/19039344679
in .github/actions/configure-docker/action.yml:9 in 7632e0ba31

The GHA docs do not mention inputs.<input_id>.options at all.

willcl-ark commented at 5:14 PM on November 3, 2025:

Yep, I think the original implementation got wires crossed with workflow dispatch inputs https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#example-of-onworkflow_dispatchinputs

Didn't look at the second commit, which is written in Bash, but I guess this is harmless and fine either way.
