Investigate how to get actionlint to do better

[krsna-m]

#109 disables actionlint on composite actions (there is an open feature request for this rhysd/actionlint#46) also it disables shellcheck from actionlint which we don't want, but it is throwing shellcheck errors which should not be there:

Strangely running using the same workflow on the actionlint playground does not have the shellcheck issue (It appears shellcheck is not ran in the playground)... permalink
