utils: fix date and time format retrieved from the module source dir (#…

…2595)

Same date and time format `"%A %b %d %H:%M:%S %Y"` (example
Wednesday Oct 05 06:42:36 2022) inside manual page for all use cases:

1. Core modules compiled from Git repository, with date and time retrievied
from the last commit.

2. Core modules compiled from tarball without Git repository and without
applied official patch core_modules_with_last_commit.patch, with date and
time retrievied from the module source directory.

3. Core modules compiled from tarball without Git repository and with applied
official patch core_modules_with_last_commit.patch, with date and time
retrievied from the core_modules_with_last_commit.json file.

4. Official addons with date and time retrievied from the last commit
via GitHub REST API.

5. Unofficial addons with date and time retrievied from the module source
directory.
