Incorrect branch for the deposit-cli

[montanhahide]

When I choose generate keys / build from source / install deposit-cli, there is a following text:

If you’re a git user, you can run git clone -b master --single-branch https://github.com/eth-educators/ethstaker-deposit-cli.git to download the master branch.

But this branch is not updated more than 1 year and doesn't contain latest features like --compounding option. The right branch seems to be "main" not "master".

The branch should be main instead of master.
