Permissions issue when running git clone.

[AnthonyAndroulakis]

Describe the bug
When git cloning the repository, 2 permissions issues come up.
When the repository is cloned (ie when running git clone --recurse-submodules git@github.com:niivue/niivue-desktop.git), the following logs are printed:

Cloning into 'niivue-desktop'...
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

If, instead, a modified version of the command is used to git clone (ie git clone --recurse-submodules https://github.com/niivue/niivue-desktop.git, the 2nd issue of cloning the submodule shows up with the following log:

Cloning into 'niivue-desktop'...

To Reproduce

1. Run git clone --recurse-submodules git@github.com:niivue/niivue-desktop.git to see the 1st permissions error
2. Run git clone --recurse-submodules https://github.com/niivue/niivue-desktop.git to see the 2nd permissions error

Expected behavior
niivue-desktop should be git cloned successfully without permission errors.

An example installation log should look like:

Closed. This was actually an issue on my end (I did not set up git correctly).
