[Bug] Date parsed incorrectly when format includes time offset

[UvixCreative]

Describe the bug
When adding a feed which uses the time format hh:mm:ss +0000, the app parses each item in that format as being published "today."

To Reproduce
Steps to reproduce the behavior:

1. Add a feed (example: https://letterboxd.com/davidehrlich/rss)
2. Go to the feed from the sidebar

Expected behavior
pubDate property gets properly parsed and items show the date/time they were published

Environment information (please complete the following information):

• Account type: local
• App version: 2.1.1
• Android version: Android 16 (GrapheneOS)
• Device type: Google Pixel 8
• Store: F-Droid
• Stacktrace collected from crash screen

Additional context
I compared one working feed to the broken feed from letterboxd. The date format in both were identical, except that the working feed ended with "GMT" after the time and the broken feed had +1300

Documenting my own research:

RSS does support timezone offset (±hhmm): https://stackoverflow.com/questions/11993258/what-is-the-correct-format-for-rss-feed-pubdate#25011375

This is the code responsible for Readrops:

Readrops/db/src/main/java/com/readrops/db/util/DateUtils.kt

Line 51 in 9ebbe03

* @return parsed date or [LocalDateTime.now]

It looks like the code should already be accounting for this format with OFFSET_PATTERN, and Z is the correct syntax for that:

https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html

I haven't gotten to test this in a real environment yet, but everything looks right to me, I don't know why the offset wouldn't be parsed...
