UPDATED: Add closing section: include non-technical support/helps/ideas

[chalmerlowe]

Add a final section/file (i.e. section 6).

Include some commentary about the reality of supporting sprints:

this blog article has some very good ideas... https://treyhunner.com/2019/04/making-the-most-of-the-pycon-sprints/

Some ideas include:

• leaving a group to work on a different sprint is OK
• approaching a group and asking them to describe their project is OK
• asking the project developer is OK >>> in fact, more than OK. In most cases, they have allocated their time to welcoming and helping new sprinters ... you aren't bothering them... you are giving them something to do.

Suggest conclusion.md as a filename

The general idea is to leave the attendee with:

• a nice conclusion to the workshop
• some encouraging words
• sage advice

NOTE: this will also require an edit to the table of contents file: toc.py
