Shorten the pseudo-version length of Use release date as version string setting

[RestAFK]

Describe the feature

The current pseudo-version format is too long and has duplicate "000000"s after the version.
(e.g.
2024-12-31 10:58:34.000 > 1735610314000000
2024-12-31 10:58:36.000 > 1735610316000000)

So, to reduce the pseudo-version length, I would like to simply remove the duplicate "000000" or change the display format to within 6-8 digits.
(e.g.
2024-12-31 10:58:34.000 > 1735610314
2024-12-31 10:58:36.000 > 1735610316
It seems difficult to reduce it by more than 10 digits..)
