Modify splash screen auto-hide behavior

[kevinmartin33]

-- iOS
Added a condition to only auto-hide the splash screen if not forced to keep it visible until an explicit hide() is called.

-- Android
Add compatibility with RN 0.81 / Safely retrieves the Activity (nullable) and passes it to hide()

What do you think, can you merge this PR?
In current version android doesn't build because of this row:

SplashScreen.hide(currentActivity)

Thank you in advance!

Also I would have another question:

setupCustomLottieSplash is not available on ios and 3.0.1 is not available on npm. Can I ask you to check these?
Thank you in advance!

Thank you very much for your collaboration, and sorry for the delayed response.

The forceToCloseByHideMethod flag controls whether the manual hide method is enabled or disabled. I removed the previous behavior intentionally to achieve this.

If you think we need a different approach for the hiding behavior, I’d suggest adding a separate switch for it - maybe an attribute like hideOnlyByRN.

Do you think it makes sense?

@attarchi

Thank you, it makes sense. What do you think, I should open a new PR only for the android fix?

Also can you check why setupCustomLottieSplash is not available?
