chore: fix releasy test tracking branch from main to master (#1460)

As it can be seen from FuelLabs/fuels-rs#1174
releasy only worked for self commits so far. This is because we were tracking
the wrong branch from this repo. This PR fixes the tracking branch for this repo, from
`main` to `master`.
