fix(editor): should add HTTP protocol into link automatically (#11934)

Closes: [BS-3291](https://linear.app/affine-design/issue/BS-3291/工具栏展开时报错，链接无法点击打开)

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **New Features**
  - URLs entered without a protocol (e.g., "github.com/...") are now automatically normalized to use "https://", ensuring links are secure and consistently formatted.

- **Bug Fixes**
  - Improved handling and validation of links to prevent issues with missing or invalid protocols in bookmarks and inline links.
  - Simplified URL validation logic by leveraging native URL parsing, removing complex regex and email-specific checks.
  - Streamlined toolbar link actions to operate only on valid normalized URLs.
  - Refined URL detection in markdown preprocessing to exclude lines containing spaces from being treated as URLs.

- **Tests**
  - Added tests to verify that links without a protocol are correctly normalized and displayed across different views.
  - Updated URL validation tests to better reflect valid and invalid URL formats, including IP addresses and domain variants.

- **Style**
  - Updated snapshots to reflect the use of "https://" in links.
