Pip install yamllint failing during Docker build

[fenech]

I've noticed that the Docker build of this action is failing:

Collecting yamllint>=1.25.0

However, it is also possible to install yamllint directly from Alpine packages (current version: 1.31.0-r0), which would shorten the RUN line to just:

RUN apk add --no-cache bash yamllint

This fixes the build. I'd be happy to open a PR if you like.
