'\' used to escape a '_' in the URL is invalid according to MD051

[FlorentPoinsaut]

The '' character used to escape a '_' character in the URL is invalid according to MD051.

Example : [nfs](#module\_nfs) is invalid

But if I try here, it is correctly interpreted: https://spec.commonmark.org/dingus/?text=%5Bnfs%5D(%23module_nfs)%20%0A&smart=1

Is this deliberate behaviour?
I'm wondering because this breaks compatibility with terrafom-docs and I'd like to know whether I should ask them to correct this or not :-D

It should be unnecessary to escape the underscore in that scenario, but I need to look at the specifications to see if it's wrong to do so. I notice that the backslash is ignored in your example and by the markdown-it parser. I will look into this more when I'm not on my phone.

It seems to be ignored by the micromark parser as well.

CommonMark explicitly allows backslash escapes in link destinations: https://spec.commonmark.org/0.30/#example-22

Thank you so much for your responsiveness and all your hard work!
