Display full content of the gitconfig on the dashboard

[RomanNikitenko]

Is your enhancement related to a problem? Please describe

It's possible to edit gitconfig from the dashboard: User Preferences => Gitconfig => Import Git Configuration.
It's very useful for me, I also think we could improve that functionality.

For example, I added alias section to the config, like:

[alias]
    co="checkout"
    br="branch"
    st="status"

The changes were applied, but they were not displayed on the Gitconfig page.

Describe the solution you'd like

As far as I understand, currently only user section is displayed on the Gitconfig page.
As an improvement we could display full content of the gitconfig.

Describe alternatives you've considered

No response

Additional context

as a workaround: it's possible to see full content of the gitconfig using Import Git Configuration button:
