fix: synthetic tx parsing for pox2 bitcoin-ops (#1505)

* chore: bump to stacks-node 2.1.0.0.0-rc1 working branch

* test: integration test to reproduce StackStx Bitcoin-op error

* chore: cleanup btc tx construction

* fix: bug in parsing STX Operations on Bitcoin for Stacks 2.1

* test: cleanup integration tests

* ci: lint fixes

* chore: revert accidental debug config change

* chore: bump stacks-node image to version with btc wallet priv key config

* test: ensure synthetic stx-stack tx obj is generated with correct values

* test: fix expected values in synthetic stack-stx tx test

* test: add test for delegate-stack burnchain op

* fix: patches to pox-2 transition tests to work with latest stacks-node 2.1 behavior
