feat: bumped frontend-platform to v6

[BilalQamar95]

Description
Bumped frontend-platform to v6 which includes major version upgrades bumping paragon to v21, react-redux to v8.1.1 & react-intl to v6.4.7

Merge checklist:

• Evaluate how your changes will impact existing consumers (e.g., frontend-app-learner-portal-enterprise, frontend-app-admin-portal, and frontend-app-enterprise-public-catalog). Will consumers safely be able to upgrade to this change without any breaking changes?
• Ensure your commit message follows the semantic-release conventional commit message format. If your changes include a breaking change, ensure your commit message is explicitly marked as a BREAKING CHANGE so the NPM package is released as such.
• Once CI is passing, verify the package versions that Lerna will increment to in the Github Action CI workflow logs.
  • Note: This may be found in the "Preview Updated Versions (dry run)" step in the Github Action CI workflow logs.

Post merge:

• Verify Lerna created a release commit (e.g., chore(release): publish) that incremented versions in relevant package.json and CHANGELOG files, and created Git tags for those versions.
• Run the Publish from package.json Github Action workflow to publish these new package versions to NPM.
  • This may be triggered by clicking the "Run workflow" option for the master branch.
• Verify the new package versions were published to NPM (i.e., npm view <package_name> versions --json).
  • Note: There may be a slight delay between when the workflow finished and when NPM reports the package version as being published. If it doesn't appear right away in the above command, try again in a few minutes.

LGTM, so long as it's verified that consumers of these NPM packages can still either use v5 or v6 of frontend-platform given both are listed as possible peer dependencies. Based on the release notes for v6 frontend-platform, seems like it should be a non-issue to support both here (no breaking change needed?).

I don't think a breaking change is needed here, we also did do some preliminary consumer testing & they were working fine
