patch 9.1.0016: default diff highlighting is too noisy
Problem: default diff highlighting is too noisy
Solution: Link diff highlighting groups to new
Added/Removed/Changed, revert previous change
(Romain Lafourcade)
Remove diff* links added in #13776 and doc added in commit b1392be
The links added in #13776 are way too noisy for the contexts in which
the `diff` syntax is applied (git commits, patches, etc.).
This commit:
- removes those links
- adds new default highlighting groups Added, Changed and
Removed
- links the diff highlighting groups to those new defaults
- removes the doc changes
- adjusts the syntax_completion test for those newly added group
names
Note: Changes to the default color schemes will be handled separately,
by adding links to those newly created Added/Removed/Changed
highlighting groups.
