README.md: update maintainers

- I noticed this in a PR recently, maybe the maintainer didn't think
  they would have to run `brew man` for this? In that case there's an
  extra step after the PR is raised, red CI checks on the PR (which is
  demoralising) and potentially requires a reviewer to point this out.
- This runs `brew man` if the `README` file has a diff as part of this
  command. Then the user has to `git add .` and their PR is (probably)
  good.

fix(tap): set clone remote name to origin explicitly

Git now allows setting a different default remote name than `origin`
when you do a fresh clone by running:

```shell
git config --global clone.defaultRemoteName notorigin
```

This causes `brew tap <tap_name> && brew update` to fail, as it clones
with a different remote name in the `tap` and then expects the remote to
be `origin` in the `update`.

Fix this by explicitly setting the origin remote in the clone command.

Some conflicts are os-specific.

Fixes #10170 by preferring gcc@5 on linux
This makes sure ENV.cc and ENV.cxx is correctly set:

If a formula does not explicitely depend on a brewed gcc,
ENV.cc is set to gcc-5 (system gcc-5 or brewed gcc-5) with this change,
even if other gcc versions are installed on the system.
