Links are not detected after enter and in custom blocks

[jakubriedl]

Describe the bug
Hi,
I'm currently having 2 issues with links experience, possibly caused by autolink helper from tiptap

1. link url is detected only when user hits space after it, when they hit enter the link isn't detected
2. in custom block (including the Alert example in docs) the links are not detected at all

To Reproduce

1. in demo on homepage enter url in block and hit enter, it won't get detected same as with space
2. in custom block demo (alert) try to type url and hit space, it won't get detected

Misc

• Node version:
• Package manager:
• Browser: Chrome
• I'm a sponsor and would appreciate if you could look into this sooner than later 💖
