.github/workflows: Avoid specifying the paths-ignore keyword (#2511)

Update the CI-related workflows and avoid specifying the paths-ignore
keyword. Because we have configure required status contexts through
branch protection rules, any workflow that is skipped due to path
filtering results in an unknown status, which results in tide stalling
any merge despite a PR matching the merge criteria (e.g. lgtm/approval
label present).

This is a short term fix to the solution: the long term
solution is dynamically filtering out certain file paths as a
pre-requisite job vs. statically filtering using the paths-ignore
filter, while we wait for GitHub to add this as first-class functionality.
