Turn off wait for Firefox Addon approval

I don't think it makes sense to have the GitHub action stuck waiting for approval.
As seen here: https://github.com/jetersen/bamboohr-timesheet-extension/actions/runs/10073728059/job/27848399925

Note that the source of the workflow is actually at https://github.com/fregante/ghatemplates/blob/main/webext/release.yml as the header comment suggests. Please make PRs towards that so I don't have to manually carry them over later on.

As for this, I'd rather keep it as a default of this workflow. Nothing happens afterwards so nobody is waiting for this to end.

As luck would have it, my last deployment failed and this timeout would have probably hid this result:

Fair enough
