[doctor] clean up check names

How

Changed the check names as suggested, trying to explain a little more specifically/ plainly what they were doing.

In the long run, I kind of want to get away from these descriptions entirely. They were originally an attempt to componentize things that were tested together, but now they result in sometimes having to worry about how the technical category (e.g., a deep dependency check) matches or doesn't match with the logical category of the check (e.g., support package version check vs. checking for unimodules, various categories of things that could all be considered "package.json checks", etc.).

• Validate Expo Config - capital C
• Check for conflicting global packages says 'in project', the incompatible packages one doesn't
• I don't understand what line 9 is trying to say
• What's the difference between 'check', 'validate' and 'verify'?
