refactor(devins-lang): add support for browsing web content with new command /browse

This commit introduces a new feature to the `devins-lang` extension, allowing users to browse web content using the new `/browse` command. The command is implemented in `BrowseInsCommand.kt`, which now includes a `runInEdt` block to ensure thread safety when parsing and retrieving the body of the web content.
