Strikethrough with <s> instead of <del> doesn't get rendered at all

[SteffoSpieler]

Bug Description

When sending a message with strike-through text, some clients use <s> instead of <del>, which results in the text not being rendered in FluffyChat.

Steps to Reproduce

1. Send a message with <s> as strikethrough (e.g. via the /html command or with other clients like Cinny)
2. See the text not being rendered at all.

Expected Behavior

I'd expect to see the text and it being striked through.

App Version

1.25.0

Additional Platform Information

Google Pixel 7 Pro running Android 15

Additional Context

Screenshots showing the test messages:

<s> is also part of the matrix spec.
