Real names for people who requested safekeeping of their commit bits.
Compare with the same past report.

Include the resignation of my doc commit bit.  Express this in the same
way as the safekeeping of Sergey Kandaurov's doc commit bit.

The new Weblate server was a server, not a person (should not be
amongst the list of humans who perform translation).

Moreover: the Weblate server was new in April (last quarter, not this
quarter). So, don't repeat the news.

Fix URLs.

Uppercase USES (not Uses), and no need to repeat the word 'New'.

Markup: remove unnecessary white space before list items.

Some punctuation.

Another discrepancy should become clearer, in GitHub, following these
changes.

Fixes: aed40a9 Status/2023Q3/doceng.adoc: Add report
Pull-request:   freebsd#271

Fix the markup, in my previous commit, for the two USES list items.

In the USES context, remove white spaces. Consistent with
https://docs.freebsd.org/en/books/porters-handbook/book/
the FreeBSD Porter's Handbook, which never exemplifies 'USES ='.

Consistency: Americanise headings.  Some were already Americanised.

Where a heading is followed by a single sentence that ends with a
colon: remove the trailing colon from the heading.

'Three new translators' was followed by a list of four.

Assume that the list is true, fix the number.

'four phases:' was followed by a list of three. 

Assume that three is true.  Correct the number.
