[Enhancement] [Peek] Allow setting file extensions to preview as raw text

[honhimW]

Description of the new feature / enhancement

I would like to request an enhancement to the existing Peek functionality. There are many file types (extensions) that are essentially text files but are currently (or in the future) not supported for preview, such as: .g4, .interp, .tokens. Even without syntax highlighting, being able to quickly preview these files would be very beneficial. Additionally, given that .csv preview is still not supported in version 0.83.0, allowing .csv files to be set as text files for preview would be a good interim solution.

Scenario when this would be used?

• Custom file extensions;
• Personal file extensions;
• Future file extensions (new programming languages);
