doc: avoid _may_ in collaborator guide
Browse files Browse the repository at this point in the history
Many style guides (including Microsoft's) suggest avoiding _may_ because
it can be unclear. Using _can_ or _might_ tends to increase clarity.

An example in this change:

> They may not change to a Runtime Deprecation until the next major
> release.

It's not clear if that means "They can not change until the next major
release" or "They might not change until the next major release but also
might change before then". Using _can_ or _might_ instead of _may_
clears up the ambiguity.
