Add option to set ssh port for servers using non-standard SSH port

[romainreignier]

Hi dear maintainers,

I know that this action has been developed exclusively to be used on Github.
But other forges like Forgejo provide actions runners compatible with the Github ones.
I have been able to use your action on a private Forgejo instance but on my server, the SSH port of the Git server is not the default port 22. Hence my rosinstall files contains ssh urls with a specific port, in the format:

ssh://git@domain_name.com:port/org/repo.git

instead of the Github:

[email protected]:org/repo.git

By adding the ssh-port input for the action, I have managed to adapt the url replaced with the insteaof git config to make it work for my use-case.

Because the git url with a port has already a trailing / like on HTTPS urls, the config entry is the same, hence the --add argument in that case.

I have not added an entry in the README because this is an advanced usage of the action and it is documented in action.yml.

I have been able to test this change both on my private Forgejo setup and on Github with a private repo with ssh url in the rosinstall.

Seems reasonable to me. I just have a minor request.

[christophebedard]

I think git-ssh-port would be a bit more descriptive, for the input name here and for the variable (gitSshPort) in src/action-ros-ci.ts

[romainreignier]

This seems a good idea.
I won't be able to make the change this week but will try I soon as I can or feel free to do it.
