PEP 750: major updates to "Template Strings" based on community feedback

[davepeck]

• Change is either:
  • To a Draft PEP
  • To an Accepted or Final PEP, with Steering Council approval
  • To fix an editorial issue (markup, typo, link, header, etc)
• PR title prefixed with PEP number (e.g. PEP 123: Summary of changes)

This PR contains substantial updates to PEP 750 based on feedback from the broader Python community, including comments on the official PEP Discourse thread and in-person core team feedback at the recent Bellevue, WA, USA sprint.

It has been reviewed by:

• @lysnikolaou (in progress)
