Stop using deprecated Bitbucket function of the provider API library

[sergeibbb]

If your team's product uses gitkraken/provider-apis's Bitbucket functions, please upgrade to v0.39.0 and migrate away from the deprecated functions. The deprecated functions use endpoints that will cease working at the end of the month.

@sergeibbb - Upgraded to P0 as we need this completed and released before the end of the month.
