[Chore] Update CF API version to latest

[davewalter]

Background

In the presenter for the root API endpoint, we specify the version of the CF API that Korifi implements. Currently, this is set to 3.117.0+cf-k8s. Since we last updated this version in #1205, the current CF API version provided by capi-release has moved forward to 3.149.0 (as of the time of writing this chore).

Action to take

• Review the changes made to the CF API since 3.117.0 to determine what changes have been made to the CF API
  • capi-release release notes
  • CF API v3 documentation
• Update our implementations of the CF API endpoints as required to comply with the current latest version of the CF API
• Update the root endpoint presenter to return the new version

Impact

Version 8 of the CF CLI supports CF API version 3.99.0 and above, but version 9 will presumably bump this forward. To ensure compatibility, we should keep our CF API version up to date.

Dev Notes

See #1205 for the last time we bumped the CF API version.
