[PATCH 2/4] Documentation: list all type specifiers in config prose

[Taylor Blau <me@ttaylorr.com>]

The documentation for the `git-config(1)` builtin has not been recently
updated to include new types, such as `--bool-or-int`, and
`--expiry-date`. To ensure completeness when adding a new type
specifier, let's update the existing documentation to include the new
types.

This commit also prepares for the new type specifier `--color`, so that
this section will not lag behind when yet more new specifiers are added.
