[BUG] Text shown when launching an unsupported version of nextgen is not accurate

[nullablepointer]

When launching a nightly build, this message shows up. The message implies that we are using an older version of liquidbounce, which might not be the case. The text could be reworded to be better. For example:

The selected version of LiquidBounce is not officially supported. We recommend using/upgrading to the latest stable version of LiquidBounce Nextgen....

The message shows when you have not selected "Latest". The message is accurate, just the button is bit wrong and should rather say "Switch to Latest now".
