ci: Fix broken Jira search block PR merges

[isivaselvan]

Rollback Plan

If a change needs to be reverted, revert this commit - it only changes CI workflow behavior, nothing in the provider binary.

Changes to Security Controls

None. This is a CI-only workflow change; no provider code, schema, or runtime behavior is affected.

Description

The Jira sync check (.github/workflows/jira-pr.yml) fails on every PR event other than opened (edits, closes, reopens). Root cause: the Search step calls tomhjp/gh-action-jira-search, whose main.go hardcodes a call to Jira's GET /rest/api/3/search endpoint — an endpoint Atlassian has since retired:

API call GET /rest/api/3/search failed (410):
"The requested API has been removed. Please migrate to the /rest/api/3/search/jql API."

Since this workflow is internal Jira-ticket bookkeeping with no bearing on code correctness, this PR marks the Search step continue-on-error: true so it stops blocking mergeStateStatus on unrelated PRs while upstream remains unfixed. The downstream steps (Sync comment, Close PR, Reopen PR) already gate on steps.search.outputs.issue, so when Search fails without setting that output, they skip cleanly instead of the job erroring.

Same fix, same root cause, already applied to the sibling terraform-provider-kubernetes repo: hashicorp/terraform-provider-kubernetes#2958.

Scope note: .github/workflows/jira-issues.yml has the identical pattern and will fail the same way, but is intentionally left out of this PR to keep the change scoped to what's actually blocking PR merges — same scoping decision made in the companion k8s-provider fix.

Acceptance tests

• Have you added an acceptance test for the functionality being added?
• Have you run the acceptance tests on this branch?

Not applicable — this is a GitHub Actions workflow change, not provider code, so make testacc doesn't apply. Verified instead via:

$ actionlint .github/workflows/jira-pr.yml
# same pre-existing shellcheck warnings as origin/main (unrelated Set-ticket-type
# script quoting); nothing new introduced by this change

$ act workflow_dispatch -W <synthetic repro workflow> -P ubuntu-latest=catthehacker/ubuntu:act-latest
# reproduced the exact step/output mechanism locally against Docker:
# Search step fails (continue-on-error: true) -> "Failed but continue next step"
# downstream step gated on steps.search.outputs.issue -> skipped cleanly, never runs
# job result -> "Job succeeded"

Release Note
