Update UI for 'Present' mode

### Description

In Code documents shared in 'Present' mode, the option to browse History appears although it doesn't work when the user attempts to do so (no changes are reverted in the document, which stays as-is). The UI should be updated to remove the 'History' option for Code documents shared in this mode.

### Steps to reproduce

1. Create Code document
2. Make changes
3. Share in Present mode
4. In the shared document, when browsing history is attempted, nothing changes/no content is reverted

### Relevant logs

```shell

```

### Expected behavior

The History option should be removed from the File dropdown menu for users viewing the document in Present mode.
