docs: add 0.21 release note for bitcoind miner tests
What changed, and why it matters
This commit only adds a release note describing new test infrastructure. It documents that the project's integration-test framework gained the ability to use a bitcoind-backed miner backend, and that continuous integration now tests that combination. There is no code change, no bug fix, and no security-relevant behavior change in the software itself.
No security action needed. This is a documentation-only release-note entry.
Security signals we found
No strong security signals were identified.
