Push to Gitea not working with ssh keys

having some issues getting the plugin to work nicely using ssh keys with gitea.
Using user:pass works fine though.

I have tested with Git for windows and it works just fine.

Below is the output i get from the console.
Let me know if you want me to run any tests.
I'll see if i can find anything in the server logs.

```
core/variant/variant_utility.cpp:1092 - GitPlugin: Could not connect to remote "Origin". Are your credentials correct? Try using a PAT token (in case you are using Github) as your password. Error -1: failed to parse supported auth schemes: The operation identifier is not valid.
