6875796417 Blocked 0.* IP addresses when making oembed requests
no issue

It was possible for authenticated/trusted admin users to make GET requests to localhost via the oembed service by crafting a redirect that used 0.0.0.0.

- added the 0.* default route/routing block to the private IP regex used to block requests when we're contacting external sites
- added an additional IP or localhost check in the oembed service when fetching bookmark card data

Switch to @trghost/validator, remove validator
- Part of the effort to split Ghost down into smaller, decoupled pieces
- Moved out our internal validator tooling to a separate library
- Replaced all usage of our own tooling and validatorjs directly with @tryghost/validator
- Removed the validatorjs dependency and removed the renovate pin
- This gives us a consistant, smaller, clearer public API for validations
- It will eventually be used on Ghost Admin too
- This way we can start getting up to date with validator whilst not increasing build size

Renamed validation to validator + better public API
- renamed our internal validation library to "validator" - which is the same as the tool it wraps
- updated the public api so that validator methods are directly exposed
- this will make it a drop-in replacement for validator-js
- in turn, this allows us to pull this out into @tryghost/validator, and use our own wrapper instead of the 3rd party library

73429589bd Reverted to previous user-agent for bookmark and oembed requests
no issue

- need to document changes so that external systems can adapt to the revised user-agent

Merge pull request from GHSA-4m2q-w26j-h268
no issue

- added an `externalRequest` lib
  - uses same underlying `got` module as our `request` lib
  - uses `got`'s `beforeRequest` and `beforeRedirect` hooks to perform it's own dns resolution for each url that's encountered and aborts with an error if it resolves to a private IP address block
  - includes a bypass for Ghost's configured url so that requests to it's own hostname+port are not blocked
- updated v2 and canary oembed controllers to use the `externalRequest` lib
