Remove project stale branches

[acuarica]

The repo was configured to not Automatically delete head branches[1] after pull requests are merged.

Review current project branches to check whether they have become stale. If so, we should delete them.

The following branches have no commits ahead of main. It should be safe to delete them.

rel/brownie
fea/ethersjs
fea/fe-tests

[acuarica]

The branch cancelWithdrawRequest seems to be already included in #29. It should be safe to delete it.

[acuarica]

The rest of the branches should have a corresponding PR.

@fede-rodes to keep in the loop.

We can remove all mentioned branches, in case of need we can have a look at the old repo

[acuarica]

The mentioned branches

rel/brownie
fea/ethersjs
fea/fe-tests
cancelWithdrawRequest

were deleted.

[acuarica]

The only remaining branches coming from the old repo are

fea/56-fede
fea/fe-gateway

@fede-rodes what should we do with them?
