Support RTL notes in the webview

[VGJohn]

Description

Added RTL support to the notes that display in the webview of the EpisodeFragment and NotesFragment. dir="rtl" needs to set on the notes html for it to display correctly so check if the device locale is RTL and adding the appropriate tag to the html body.

Fixes #109

Testing Instructions

1. Set the device language to RTL language
2. Open podcast episode
3. See that the notes in the webview are aligned RTL

Checklist

• If this is a user-facing change, I have added an entry in CHANGELOG.md
• I have considered whether it makes sense to add tests for my changes
• All strings that need to be localized are in modules/services/localization/src/main/res/values/strings.xml
• Any jetpack compose components I added or changed are covered by compose previews

I have tested any UI changes...

• with different themes
• with a landscape orientation
• with the device set to have a large display and font size
• for accessibility with TalkBack
