Update the GitHub CI workflow to use the bundle.sh script to pull in
Suricata-Update and libhtp. This means one less place where defaults
are hardcoded and can get out of sync.
This also simplifies the variable names that can be embedded in a pull
request message to use the same variable names that bundle.sh
expects. Of note, this removes the _PR variant, instead a branch name
of "pr/N" can be used to specify a PR.
Many places were still referencing the old Suricata page.
Used git grep with replace to update them. Checked that new links work.
Left old references when they were only documentation examples (for
output or unittests).
Task#4915
For example, to use suricata-verify pr #239:
suricata-verify-pr: 239
Also update the pull request template to contain the available
parameters that can be set.
