Check `create_release_logs()` param `until`

[marcinkowskak]

Right now, for get_release_logs() function, until parameter takes release logs released before until. It would be more convenient and natural for this parameter to take logs it released before and the same day as until.

The code below should return one record with GitStats 2.3.8 release, to see it, we need to pass until = "2025-12-09"

> release_table <- GitStats::create_gitstats() |>
+   GitStats::verbose_off() |>
+   GitStats::set_github_host(
+     orgs = "r-world-devs"
+   ) |>
+   GitStats::get_release_logs(
+     since = '2025-12-08',
+     until = '2025-12-08'
+   )

This change should also be applied to other functions making use of until, i.e.: get_commits() and get_issues().
