fix: use always() so deploy-to-ic runs when publish-versioned-docs is skipped

[marc0olo]

Problem

After #443 merged, deploy-to-ic still wasn't triggering on pushes to main. The run 23236250900 shows deploy-to-ic as skipped.

Root cause: GitHub automatically skips dependent jobs when any needed job is skipped, regardless of the if: condition. On main branch pushes, publish-versioned-docs is correctly skipped (it only runs on v* tags and docs/v* branches). But this cascades and also skips deploy-to-ic.

Fix

Add always() to the if: condition to opt out of the cascade-skip behavior, while keeping explicit guards against failures and cancellations:

if: always() && github.event_name != 'pull_request' && !contains(needs.*.result, 'failure') && !contains(needs.*.result, 'cancelled')

This ensures:

• ✅ Runs on main push (even though publish-versioned-docs is skipped)
• ✅ Runs on tag/docs/v* push (all three publish jobs ran)
• ✅ Skipped on PR builds
• ✅ Skipped if any publish job failed or was cancelled
