[ci] Look for any tags in issues before adding new tags (apache#10685)

Previously this searched for a specific `cc @abc` line by itself before looking for people to tag. This led to a double-tag in apache#10679. The change here updates it to check for `@`-ed people anywhere in the PR/issue body and filters those out.
