cva6-sdk host key verification failed on git submodule update --init --recursive

[rseac]

Hello,

I get the following error when running git submodule update --init --recursive.

Cloning into '/ara/cheshire/sw/cva6-sdk'...
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
fatal: clone of 'git@github.com:moimfeld/cva6-sdk.git' into submodule path '/ara/cheshire/sw/cva6-sdk' failed

I believe the problem is with the .gitmodules url for cheshire/sw/cva6-sdk. It currently has

url = git@github.com:moimfeld/cva6-sdk.git

but from the history it seems like it should be

url = https://github.com/pulp-platform/cva6.git

Is this correct? I'd be happy to open a PR, if this is the case.
