Allow text files to be edited even when empty (#1724)

* fix: allow text files to be edited even when empty

* wip: remove the need for loading file contents into memory

* xcode updated packages

- CodeEditTextView 0.7.3 -> 0.7.4
- CodeEditSourceEditor 0.7.2 -> 0.7.3
- CodeEditLanguages 0.1.18 -> 0.1.19

* Merge branch 'main' of https://github.com/CodeEditApp/CodeEdit into allow-edit-text-file-when-contents-in-empty

* remove extra checks in `CodeFileDocument.utType`

Only check for when `CodeFileDocument.content` is not nil. If the content is an empty string, it means we're viewing an empty text file, which is a predictable behavior. Also, the extra checks cause unexpected behaviors. Check the related pull request (#1724) for visuals.

* redo changes made in 45c39ce
