extending detection of setting of $GITHUB_OUTPUTs

[tomsit-ionos]

Is your feature request related to a problem? Please describe.

Given that an output is set via tee like so:

echo "dev_version=$DEV_VERSION" | tee -a $GITHUB_OUTPUT $GITHUB_STEP_SUMMARY

Then dev_version is not recognized as valid step-output resulting in a false warning/error

Describe the solution you'd like
setting values in an $GITHUB_OUTPUT can happen in a lot of ways (CLI commands).
It's hard to support them all i guess but i think supporting a generic approach (maybe even config'able or easily extensible) would be great.

One shot might be to look for an regex like so: \|.*(\$GITHUB_OUTPUT|\$\{GITHUB_OUTPUT})
