Ivadomed: Improve Community Guidelines

[charleygros]

Currently, Community Guidelines are in:

• https://ivadomed.org/en/latest/contributing.html
• the repository wiki

It would be nice to also

• have a file, eg CODE_OF_CONDUCT.md --> only point to the available resources
• have issue and Pull-Request templates pointing to the relevant parts of the wiki

I wonder if the reviewers meant CONTRIBUTING.md instead of CODE_OF_CONDUCT.md. Because, CODE_OF_CONDUCT.md is more for... standards of behavior? Fostering a welcoming environment through kindness, respect, and handling conflict/discrimination/harassment. For example: https://github.com/tensorflow/tensorflow/blob/master/CODE_OF_CONDUCT.md

Code of conducts are lovely, but from context it seems like they meant contributing guidelines, so I'm not sure.

Assuming they did mean CONTRIBUTING.md, then we can do what SCT does.

• Move the ./docs/source/contributing.rst file to ./CONTRIBUTING.rst (so that it is visible to reviewers).
• Use a symlink for ./docs/source/contributing.rst that points to the base-level file.

That way, the information is visible in both locations.

Makes a lot of sense and sounds great! Thanks @joshuacwnewton for taking care of this
