chore(oui): Bump OUI dependency to 1.2.0, remove breadcrumb styling

[joshuarrrr]

Description

Bump OUI version - don't merge until we update from release candidate.

OUI 1.2 includes all necessary breadcrumb styling, so OpenSearch Dashboards customizations are no longer necessary. So we're also essentially reverting the changes from:

• [UX] Restyle global breadcrumbs #1954
• [Bug] Fix Global Breadcrumb Styling in dark mode #2085

Issues Resolved

Testing the changes

Check List

• All tests pass
  • yarn test:jest
  • yarn test:jest_integration
  • yarn test:ftr
• New functionality includes testing.
• New functionality has been documented.
• Update CHANGELOG.md
• Commits are signed per the DCO using --signoff

[joshuarrrr]

Converting to draft until v1.2.0 is released. But we can run the CI against the release candidate.

I opened a separate PR for the Link Checker failure: #4171

Breadcrumbs probably look wonky with current changes. New breadcrumb styling went into 1.2, so the styling is most likely being applied twice. I outlined how to fix in here: opensearch-project/oui#796 (comment)

[joshuarrrr]

Thanks @BSFishy for the instructions - I'll update the PR accordingly.

Discussed with @KrooshalUX:

Since anywhere project got bumped from 2.8 release. This PR is not required to get in and bake longer.

I noticed the breadcrumb got a little bit blurrer:

From playground: with expanded header turned off:

After, my local with expanded header default value:

Converting to draft - we'll split the OUI changes into different releases so we can pull a clean v1.1.1 with just the icon changes.

This is ready for re-review. Discussed with @AMoo-Miki and we're ok to take some of the breadcrumb concerns in #4457 as a blocker for this in the 2.x line, but we'll go ahead and merge to main so we can further test and validate prior to the 2.10 release.

@joshuarrrr Do you want to solve the conflicts? and also there are some test fails

[joshuarrrr]

Closing in favor of #4621 - no need to bump to OUI 1.2, since we've already bumped main to OUI 1.3-rc.
