Ansible lint fixes

This is an attempt to make ansible-lint happy.

Reference: https://ansible-lint.readthedocs.io/en/latest/default_rules/#var-naming

We don't really fix these, but just suppress them,
because they're like that intentionally.

We try to name variables in a way that is consistent with the
configuration key they control. If the upstream component uses
camelCase, we also need to include camelCase in the variable name.

One that doesn't trip up ansible-lint, causing `load-failure` errors.

Reference: https://ansible-lint.readthedocs.io/en/latest/default_rules/#var-spacing

Reference: https://ansible-lint.readthedocs.io/en/latest/default_rules/#git-latest

Our variable naming is not necessarily consistent across roles.
I've tried to follow the naming conventions of each individual role.
All new variables are suffixed with `_version`, but the prefix may be
somewhat different.

This does 2 things:

- it fixes the syntax for `matrix_id`. Starting strings with `@` is
  invalid YAML, so such strings need to be wrapped in single or double
  quotes
- it makes use of the `matrix_domain` variable instead of hardcoding the
  domain name. This should be more and mistake-proof (typos or people
  mistaking their domain - matrix. vs base domain)

`|to_json` already adds the surrounding double-quotes for the string, so
adding them explicitly means we've got a double-quotes problem.
