Add dir="auto" to cards for stable card direction

[MoamenAbdelsattar]

Purpose / Description

Currently, the direction in which a card is rendered is not stable by default. If the UI of Ankidroid is English, text direction is left-to-right by default. If the UI of Ankidroidis Arabic, text direction is right-to-left by default. Although this can be changed from the settings (changing css for example), the card direction should be stable by default, being viewed in the same way regardless of the direction of the UI.

Fixes

This commit makes the direction of cards stable, regardless of the UI language.

Approach

This commit attempts to solve the issue by adding dir="auto" by default for all cards. It will not break existing cards that override the direction via css or html, but it will make cards that don't specify a direction stable.

How Has This Been Tested?

I haven't built Ankidroid, but I tested adding this attribute to card template front and back and it worked correctly, making the card direction stable regardless of the UI language.

Thanks!!

This would need to be handled upstream so we don't deviate from how Anki Desktop renders cards.

Ideally make an issue, or a message on this PR with evidence that we're currently not matching Anki Desktop

Hi there 👋 - quick question - how does Anki Desktop handle this same case?

[MoamenAbdelsattar]

I tested Anki desktop and found it has the same issue (card direction depends on the UI language). I made a PR there:
ankitects/anki#4428

[mikehardy]

Excellent - FWIW, this looks to me like an obviously good idea, I just want to make sure we behave the same as Desktop, no one likes surprising differences between the platforms. If upstream agrees it is a good idea and merges we can do the same here pretty much immediately. Cheers

Thanks!!!! Closing this until upstream's fix is accepted.
