[PATCH v2 10/13] config: format expiry dates gently

From

Message-ID
<9221ca2352d65f3cbdec00f7577089c734799919.1771026918.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.2044.v2.git.1771026918.gitgitgadget@gmail.com>
From: Derrick Stolee <stolee@gmail.com>

Move the logic for formatting expiry date config values into a helper method and use gentle parsing when needed.

There is an unfortunate asymmetry in these two parsing methods, but we need to treat a positive response from parse_expiry_date() as an error or we will get incorrect values.

This updates the behavior of 'git config list --type=expiry-date' to be quiet when attempting parsing on non-date values.
