Subject: [PATCH] fix(datetime): navigating months in RTL works correctly
 (#29421)

Issue number: resolves #29198

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

In https://github.com/ionic-team/ionic-framework/pull/27917 I failed to
account for RTL. This caused the navigation with the arrow buttons to
break because the scroll position was always < 2.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Datetime now checks if the component is in RTL mode when creating the
scrollLeft threshold.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!--
  If this introduces a breaking change:
1. Describe the impact and migration path for existing applications
below.
  2. Update the BREAKING.md file with the breaking change.
3. Add "BREAKING CHANGE: [...]" to the commit description when merging.
See

## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->
