the idea is to have a markdown convention that will link to the two repos we already backport from and include the bitcoin-core/gui repo
after this diff I establish the following convention:
summary text in the format LOWERCASE_SUPPORTED_REPO_PREFIX#PR_NUMBER will be replaced with a link to the appropriate PR if LOWERCASE_SUPPORTED_REPO_PREFIX is in the relevant dictionary in server.py
examples:
core#17234 should replace to [[https://github.com/bitcoin/bitcoin/pull/17234
| core#17234]]
core-gui#9 to [[https://github.com/bitcoin-core/gui/pull/9
| core-gui#9]]
and secp256k1#894 to [[https://github.com/bitcoin-core/secp256k1/pull/894
| secp256k1#894]]
