actions: build docs only in the upstream repo (not in private forks)

This should stop contributors receiving the "deployment failed" e-mails.

Shouldn't it be inside ${{ }}? Like so:

if: ${{ github.repository == 'redhat-performance/tuned' }}

(See https://docs.github.com/en/actions/how-tos/write-workflows/choose-when-workflows-run/control-jobs-with-conditions)

IMHO from: https://docs.github.com/en/actions/reference/workflows-and-actions/metadata-syntax#runsstepsif:

When you use expressions in an if conditional, you can, optionally, omit the ${{ }} expression syntax because GitHub Actions automatically evaluates the if conditional as an expression. However, this exception does not apply everywhere.

But I agree it's more readable with the explicit evaluation, I will fix it.
