Remove Twitter account linking documentation (#1802)

Twitter account linking functionality has been completely removed from
both the UI and backend. This PR updates the documentation to reflect
these changes and removes all related screenshots.

**Changes made:**

- Removed all Twitter account linking documentation including the entire
linking and unlinking sections from profile settings.
- Updated 2FA configuration docs to remove Twitter as a recovery option.
- Updated privacy policy and data request documentation to remove
Twitter references.
- Removed Twitter connect functionality from shared components.
- Cleaned up 8 unused screenshot images (7 Twitter-related and 1 unused
GitHub disconnect image).
- Updated 5 screenshots to reflect the current UI without Twitter
linking support.

**Files modified:**

-
`content/getting-started/managing-your-npm-user-account/managing-your-profile-settings.mdx`
- removed Twitter linking sections
-
`content/getting-started/managing-your-npm-user-account/requesting-your-data.mdx`
- removed Twitter account reference
-
`content/getting-started/setting-up-your-npm-user-account/configuring-two-factor-authentication.mdx`
- removed Twitter recovery option
- `content/policies/privacy.mdx` - removed Twitter data collection
references
- `src/shared.js` - removed Twitter connect functionality
- Updated screenshots: `connect-github.png`, `github-remove.png`,
`github-success.png`, `link-github-account.png`, `recover-account.png`
- Deleted screenshots: `connect-twitter.png`, `twitter-authorize.png`,
`twitter-disconnect.png`, `twitter-login.png`, `twitter-remove.png`,
`twitter-success.png`, `link-twitter-account.png`,
`github-disconnect.png`

**Manual testing:**

Verify all documentation pages render correctly without broken links or
Twitter references. Check the following pages in the local development
server or staging environment:

-
`/getting-started/managing-your-npm-user-account/managing-your-profile-settings`
- should only show GitHub linking options
-
`/getting-started/setting-up-your-npm-user-account/configuring-two-factor-authentication`
- should only mention GitHub for account recovery
-
`/getting-started/setting-up-your-npm-user-account/recovering-your-2fa-enabled-account`
- support ticket section should only mention GitHub
-
`/getting-started/setting-up-your-npm-user-account/receiving-a-one-time-password-over-email`
- support ticket section should only mention GitHub
- `/policies/privacy` - should not reference Twitter data collection
- `/getting-started/managing-your-npm-user-account/requesting-your-data`
- should not list Twitter account in personal details

Confirm all updated screenshots display properly and reflect the current
UI state.

**Test results:**

No new automated tests added as this is a documentation-only change.
Existing linting and formatting checks pass successfully.
