Feature request

It would be useful to have a quiet (or verbosity) input that either suppresses non-error output or wraps the action's log lines inside a GitHub Actions log group (::group::/::endgroup::).

Motivation

When setup-uv is embedded inside a composite action alongside several other steps, its output can dominate the log. Other steps in the same composite already use ::group:: to fold their output, but there is no way to do the same for a uses: action step — GitHub Actions only allows ::group:: inside run: shells. The only current workaround is to replace the action with a manual run: step, which sacrifices the caching and convenience it provides.

Proposed behaviour

Add an optional input, e.g.:

- uses: astral-sh/setup-uv@...
  with:
    quiet: "true"   # wraps all output in ::group:: or suppresses non-error lines

Alternatively, the action could unconditionally wrap its own output in a log group (collapsed by default), similar to how many other setup actions behave.

Example context

- name: Install uv
  uses: astral-sh/setup-uv@5a095e7a2014a4212f075830d4f7277575a9d098 # v7
  with:
    version: ${{ steps.versions.outputs.uv }}
    python-version: ${{ steps.versions.outputs.python }}
    activate-environment: "true"
    quiet: "true"   # desired, not currently supported
