feat: add WebViewBuilder.with_javascript_disabled

[Simon-Laux]

add WebViewBuilder.with_javascript_disabled to disable javascript.

There are some cases where this is nessesary.
For example I need this for safely displaying HTML emails in delta chat:

• Tauri: HTML Email View deltachat/deltachat-desktop#4699

closes #986 (which was only solved for windows before)

example to try out: https://github.com/Simon-Laux/tauri-experiments/tree/main/examples/disable_js_wry

Progress

• MacOS (implemented and tested)
• Windows (implemented and tested)
• Linux (implemented and tested)
• change wry import to git branch instead of local checkout in example
• If this change requires a new version, then add a change file in .changes directory with the appropriate bump, see https://github.com/tauri-apps/wry/blob/dev/.changes/readme.md
• Ensure that all commits are signed
