Use the main branch of the codeql action

This commit switches to the bleeding edge, main branch of the
codeql action. This helps us test the action before merging all
of the new changes into main, which occurs roughly once a week.

If there are commits that introduce bugs in codeql-action, then
we will be more likely to catch it before releasing to the world
if we are using it in this extension.
