chore: simplify regex

- We already do toLowerCase(), so don't need i flag.
- We're not using the http bit, so no need to capture it.
- If there's an s, append it, if not don't. This is the same as just
  replacing http with ws:
  [http]:// -> [ws]://
  [http]s:// -> [ws]s://
  [http]x:// -> [ws]x:// -> error. Is ok.
  [http]sx:// -> [ws]sx:// -> error in both. Is ok.
- We don't want to replace protocols that do not start with http, such
  as git+https, so we can anchor at string start and leave out the g
  flag.

Much simpler -:)
