markdown: Add horizontal scrollbars to wide tables (#61745)
## Objective

Add functional horizontal scrollbars to wide Markdown tables, matching
the existing code-block scrollbar pattern.

Fixes #61437

PR was talked about in https://github.com/zed-industries/zed/pull/61698

## Implementation:
- Added a `BTreeMap<usize, ScrollHandle>` to `Markdown` for table scroll
handles, keyed by source-range start.
- During `MarkdownElement` layout, each table container is connected to
a `Scrollbars` widget configured for the horizontal axis, using a stable
ID derived from `("markdown-table-scrollbar", range.start)`.
- The inner table div uses `overflow_x_scroll()` + `track_scroll()` with
`restrict_scroll_to_axis`.
- Handles for removed tables are discarded after re-rendering.
- No public API, setting, schema, or migration changes required.

## Recording

## Release Notes:

- Improved navigation of wide Markdown tables with horizontal
scrollbars.

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
