refactor(web): save as doc & save as block action (#10833)

### TL;DR

Added "Save as doc" option to Edgeless editor actions.

### What changed?

- Renamed `SAVE_CHAT_TO_BLOCK_ACTION` to `SAVE_AS_BLOCK` and updated its title from "Save chat to block" to "Save as block"
- Renamed `CREATE_AS_DOC` to `SAVE_AS_DOC` and updated its title from "Create as a doc" to "Save as doc"
- Added `SAVE_AS_DOC` to the `EdgelessEditorActions` array, making this option available in the Edgeless editor
