chore: break down ProfileSummary into logical components

[stevekaplan123]

Description

A fair amount of ProfileSummary could be re-used by the new Sheet Viewer sidebar which displays profile data. I broke down ProfileSummary into logical components and re-used one of them, ProfileBio.

Code Changes

1. ProfileBio is re-usable as in both UserProfile and Sheets Viewer, we want to display user education, organization, and location info.
2. The existing ProfileSummary return statement is 50 lines long. I found this difficult to read, and so even though I couldn't re-use every aspect of ProfileSummary for the sheets viewer, I re-factored ProfileSummary so that we now have 3 new constants -- profileName, profileButtons, and followInfo -- that allowed me to reduce considerably the size of the return statement in ProfileSummary. I didn't make these constants into their own components because (1) profileName is too simple to be its own component and (2) profileButtons and followInfo do not conform to the spec for the sheets viewer profile.
