Simplify access instructions for community contributors

[emstruong]

Removed redundant phrase and generalized writing from contributors section.

Why:

There doesn't seem to be an obvious reason why these instructions should apply to just 'Python', so I deleted the sentence?

What's being changed (if available, include any code snippets, screenshots, or gifs):

@emstruong Yeah, this language does seem odd. I'll ask the team to make sure there's no reason for it.

@emstruong Okay, yeah, I went and checked myself, and my team (including me) are all over the repo graph, and I guarantee none of us are doing anything with Python dependencies. This is definitely a good change, and now I'm wondering how old that wording is.
