refactor(site): update BYOK link to use "View docs" on AI settings page (#25743)

Changes the "Manage deployment-wide BYOK" link on the AI Providers
settings page (`/ai/settings`) to "View docs", matching the pattern used
on the provisioner keys page (`/organizations/{org}/provisioner-keys`).

### Changes
- Swapped `Link` from `react-router` to `#/components/Link/Link` (uses
`href` instead of `to`)
- Removed `target="_blank"` and `rel="noreferrer"`: the link now
navigates in the same tab, matching the provisioner keys page convention
- Changed link text from "Manage deployment-wide BYOK" to "View docs"
