The bundled Git cannot understand ~/.gitconfig

[pravic]

When I try to use the latest ExpressLRS Configurator 1.76, I get an error during the Download stage, although the error doesn't tell anything, really:

If I switch to the Backpack section, I get a more useful error:

It comes from my ~/.gitconfig:

[branch]
  autoSetupMerge = simple

The error happens because the bundled Git is quite outdated and doesn't recognize the branch.autoSetupMerge=simple option.

To fix this, the bundled Git (being portable) should use a separate config (perhaps, empty) and should not look at the user configuration.

Expected Behavior

The bundled Git should use its own config file.

Also, errors from the Download stage should be displayed in UI.

And the logs should be more descriptive.

Current Behavior

It tries to use the system configuration which is newer - and falls with an error.

There is no error in UI - and the logs aren't helping either:

Steps to Reproduce

1. git config --global branch.autoSetupMerge simple
2. Goto Configuration
3. Press Flash

Possible Solution (Not obligatory)

To fix this, the bundled Git (being portable) should use a separate config (perhaps, empty) and should not look at the user configuration.
