MangaDex: Clean manga descriptions (#10674)

* MangaDex: Clean manga descriptions

Closes #10610

* Incrememnt mangadex.extVersionCode

* Remove bbcode cleanup utility

Since bbcode has been replaced with markdown. So, this is no longer
required

* Don't forgot to unescape html characters

bbcode might be gone but &hearts still need to be converted to ♥

* Update `cleanString` method description

* Remove trailing newlines

Using Trim takes cares of whitespace too

* Move regex to companion object

so that they dont get instantiated everytime

* Revert "Incrememnt mangadex.extVersionCode"

This reverts commit 73c89933cc36cb41fd6691641c75acf0b6f49c45.
Will be added back in a separate minor PR
