Refractr PR Checklist

JIRA ticket: https://mozilla-hub.atlassian.net/browse/SVCSE-4369

When creating a PR for Refractr, confirm you've done the following steps for a smooth CI and CD experience:

• Have you updated the relevant YAML in the PR?
• Have you checked the relevant YAML for any possible dupes regarding your domain?
• Have you checked if there are any TLS cert concerns - e.g. if the domain being redirected already exists, and it is being changed to point at refractr, is a temporary TLS 'outage' while waiting for certification via HTTP challenge okay? If not, add a note to the JIRA ticket.
• If desired, have you generated the nginx config manually to confirm updates work as expected?

The original request asks for resolving paths as well. That's something refractr appears to accomodate and so does our cert generation logic.

So pattern matching on careers.mozilla.org as an example:

- dsts:
  - if: '$request_uri ~ ^/(.*)$'
    ^/(.*)$: www.mozilla.org/careers/$1
  - redirect: www.mozilla.org/careers/
  srcs:
  - careers.mozilla.org
  tests:
  - https://careers.mozilla.org/: https://www.mozilla.org/careers/
  # - https://careers.mozilla.org/#locations: https://www.mozilla.org/careers/#locations
  - https://careers.mozilla.org/listings: https://www.mozilla.org/careers/listings
  - https://careers.mozilla.org/listings/: https://www.mozilla.org/careers/listings/
  - https://careers.mozilla.org/feed/: https://www.mozilla.org/careers/feed/
  - https://careers.mozilla.org/position/gh/12345/: https://www.mozilla.org/careers/position/gh/12345/

I think we can accommodate the request via:

# SVCSE-4369
- dsts:
  - if: '$request_uri ~ ^/(.*)$'
    ^/(.*)$: mozilladatacollective.com/$1
  - redirect: mozilladatacollective.com/
  srcs:
  - datacollective.mozillafoundation.org
  - dev.datacollective.mozillafoundation.org
  tests:
  - https://datacollective.mozillafoundation.org/: https://mozilladatacollective.com/
  - https://datacollective.mozillafoundation.org/datasets/abc123: https://mozilladatacollective.com/datasets/abc123
  - https://datacollective.mozillafoundation.org/datasets/: https://mozilladatacollective.com/datasets/
  - https://dev.datacollective.mozillafoundation.org/: https://mozilladatacollective.com/
  - https://dev.datacollective.mozillafoundation.org/datasets/abc123: https://mozilladatacollective.com/datasets/abc123

Though I've never done this before.

I see from git history @bkochendorfer has made several srcs type changes so I'll request a review from him in case I'm missing something.

Made the change as suggested. Thank you!
