**Description:**
- Validate Gate IDs: ids must be alphanumeric with dots. At a minimum we
have to disallow `,` to avoid ambiguity in the CLI, but I am being
intentionally more restrictive here
- Validate URLs: we check that a valid URL can be built from it using
the `net/url` stdlib package
- Validate versions: we check that a valid version is passed to the
`To/FromVersion` options using hashicorp's libraries and also that the
implicit version range, when defined, is not empty.
This does not change the public API types, it only adds validation.
Relates to #8220
