editor: Add file permalink support to tabs and the Project Panel (#62177)

# Objective

- Add file-level hyperlink support for opening and copying hyperlinks
for Git remote source control to project panel and tabs
- Unify the language for Git remote hyperlinks across blame, project
panels, and tabs to be similar to GitLens' definitions (which are
commonly used in VS Code)

## Solution

- Updated the Git crate to expose relevant metadata to surface new
options within the editor
- Added new options for `Open File on Remote` and `Copy Remote File URL`
to project panel/file explorer and file tabs
- Altered the blame UI options to be consistent with new labels / more
clear

## Testing

- Ran `cargo run` to boot app and manually smoke test (see proof below)
- Added unit tests for this change

 ### Permalinks
 
-Zed also has a Copy Permalink feature to create a permanent link to a code snippet on your Git hosting service.
+Zed can open or copy a permanent link to a file or code selection on your Git hosting service.
 These links are useful for sharing a specific line or range of lines in a file at a specific commit.
-Trigger this action via the [Command Palette](./getting-started.md#command-palette) (search for `permalink`),
-by creating [custom key bindings](./key-bindings.md#custom-key-bindings) for the
-`editor::CopyPermalinkToLine` or `editor::OpenPermalinkToLine` actions
-or by simply right clicking and selecting `Copy Permalink` with line(s) selected in your editor.

+For the current selection in the editor, use {#action editor::CopyPermalinkToLine} or
+{#action editor::OpenPermalinkToLine} from the [Command Palette](./getting-started.md#command-palette)
+(search for `permalink`), via [custom key bindings](./key-bindings.md#custom-key-bindings),
+or by right-clicking and selecting **Copy Permalink to Line**.
