DOP-5873: Add new oas-bump-atlas roles

[rayangler]

Ticket

DOP-5873

Notes

• Adds new oas-bump-atlas roles that will eventually replace existing oas-atlas roles. The new roles should use the URL structure of the new Bump pages. This was desired to be a separate role so that writers can update their usage in the docs when they're ready without introducing breaking changes.
• In case a staging links are needed for testing, I modified some content locally to work (there won't be examples available in prod/preprod):
  • oas-bump-atlas-tag - Go to the "Atlas Administration API" tab at the bottom and see the "Access Tracking" link.
  • oas-bump-atlas-op - See the "returns all projects" link.

Old reStructuredText:

To view the database access history using the API, see :oas-atlas-tag:`Access Tracking </Access-Tracking>`.

The following sample ``GET`` request :oas-atlas-op:`returns all projects </listProjects>` in your organization.

New reStructuredText:

To view the database access history using the API, see :oas-bump-atlas-tag:`Access Tracking <access-tracking>`.

The following sample ``GET`` request :oas-bump-atlas-op:`returns all projects <listprojects>` in your organization.
