feat!: bump `mdast-util-from-markdown` with `synckit`

close #218, drop node 12

mdast-util-from-markdown is ESM only now, synckit makes it possible to require ESM only module in commonjs without await import().

We don't want to drop Node 12 until we release ESLint v9, which will also drop Node.js 12.

Is there a reason we can't use mdast-util-from-markdown 0.8.5 for now?

[JounQin]

It requires outdated unified related packages may results conflict/duplicate dependencies.

[nzakas]

Okay, We'll still need to wait until ESLint v9 to drop Node.js 12 support. At that point, we need to update Node.js support for all packages.

@nzakas

synckit@v0.7 supports Node 12, would that be acceptable? I can patch Node v12 support back on v0.8 either.

[JounQin]

Friendly ping @nzakas

[nzakas]

We just released ESLint v9.0.0-alpha, so I think we can formally update the Node.js support for this package now.

Can you submit a PR like this? https://github.com/eslint/eslint-scope/pull/115

@nzakas

Wow, that's really a big change, I was thinking to keep compatible, not ESLint v9 only. Because in case the big breaking changes on eslint v9, I believe the migration could be very slow.

[JounQin]

@nzakas Any further discussion?

[aladdin-add]

@JounQin it has dropped node.js < 18 supports. what's the next steps here?

[JounQin]

@aladdin-add Didn't notice that, I've updated the PR accordingly.

[nzakas]

At this point, I don't think we should move further with this PR. It's not fixing any bugs and adding in a new dependency just to upgrade some other module doesn't seem like a good tradeoff.
