gfm-like is too greedy when it comes to links

[nschloe]

Describe the bug

MWE:

from markdown_it import MarkdownIt
from markdown_it.tree import SyntaxTreeNode

md = MarkdownIt("gfm-like")
tokens = md.parse("74.78.Fk")

print(SyntaxTreeNode(tokens).pretty())

Output:

<root>
  <paragraph>
    <inline>
      <link href='http://74.78.Fk'>
        <text>

Problem: "74.78.Fk" is not a link.

This problem doesn't occur with md = MarkdownIt()

Reproduce the bug

See above.

List your environment

markdown-it --version

markdown-it-py [version 3.0.0]

This is on Python 3.11.

Tip for devs: Add a --show-env parameter to markdown-it which shows all relevant packages and versions in one go.

Heya, yeh for this and #317 I would note that the parsing is using https://github.com/tsutsu3/linkify-it-py, and perhaps bugs that should be reported there, but also maybe just a difference with the parsing logic of GFM.

In https://github.com/markdown-it-rust/markdown-it-plugins.rs, which is then utilised in https://github.com/chrisjsewell/markdown-it-pyrs, I actually implemented parsing logic "faithful" to GFM.
So, if someone wants to port that here 😅

linkify-it-py behaves the same as linkify-it as per the specification.
It is not a bug that it is linked.

.fk is the country code top-level domain (ccTLD) for the Falkland Islands.
Therefore, it is automatically linked.
If you do not want it to be linked, escape it as 74.78\.Fk.

See markdown-it demo.
