[Bug] Email link's `href` is wrong

Initial checklist

• [X] I agree to follow the code of conduct
• [X] I searched issues and discussions and couldn’t find anything (or linked relevant results below)

Affected packages and versions

@milkdown/preset-gfm

Link to runnable example

Milkdown Playground https://milkdown.dev/playground

Steps to reproduce

• Enable GFM
• Input an email address directly to the editor (do not copy & paste)

Example:

test@example.com

Expected behavior

The link text and the linked email address should be the same

Example:

[test@example.com](test@example.com)

Actual behavior

The linked email address is cut off at the first character

Example:

[test@example.com](test@example.c)

The text is wrapped with <> at first, and after I put one character after the dot ., it's converted to this syntax [](). Once it's converted to [](), the linked email address inside () is no longer updated.

I'd like to fix this, but currently seems like we have temporarily removed this feature. I haven't checked the old version, but looks like it automatically transforms the link into a markdown link. And seems like gfm doesn't work like this, instead it turns a link into a href when it renders. I think we should make it like github, render it in rendering process.
