[CI] Disable dash-licenses auto-review mode

Related issue: eclipse-theia#14127

The Eclipse Foundation Gitlab token, required for dash-licenses to
automatically open IP ticket for suspicious license in dependencies.
is about to expire. Until it's replaced, we can have the workflow use
the basic mode, where dependecies with suspicious licenses are only
listed, and have to be handled offline [1].

[1]: To have dash-licenses help with opening IP tickets automatically
     e.g. after a PR license check workflow failure. Any committer can
     generate a token from EF Gitlab at the link below and set it in
     an environment variable, and then use it when running dash-licenses
     from their laptop.

e.g.

theia$ git checkout <PR branch> && yarn
theia$ export DASH_LICENSES_PAT="<token>"
theia$ yarn license:check:review
