rubocop: Use Sorbet/StrictSigil as it's better than comments
- Previously I thought that comments were fine to discourage people from
  wasting their time trying to bump things that used `undef` that Sorbet
  didn't support. But RuboCop is better at this since it'll complain if
  the comments are unnecessary.

- Suggested in https://github.com/Homebrew/brew/pull/18018#issuecomment-2283369501.

- I've gone for a mixture of `rubocop:disable` for the files that can't
  be `typed: strict` (use of undef, required before everything else, etc)
  and `rubocop:todo` for everything else that should be tried to make
  strictly typed. There's no functional difference between the two as
  `rubocop:todo` is `rubocop:disable` with a different name.

- And I entirely disabled the cop for the docs/ directory since
  `typed: strict` isn't going to gain us anything for some Markdown
  linting config files.

- This means that now it's easier to track what needs to be done rather
  than relying on checklists of files in our big Sorbet issue:

```shell
$ git grep 'typed: true # rubocop:todo Sorbet/StrictSigil' | wc -l
    268
```

- And this is confirmed working for new files:

```shell
$ git status
On branch use-rubocop-for-sorbet-strict-sigils
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        Library/Homebrew/bad.rb
        Library/Homebrew/good.rb

nothing added to commit but untracked files present (use "git add" to track)

$ brew style
