One of the linting rules is wrongly identifying 2 asterisks as italic markers.

Since these asterisks are normal text (not used to format the text as Italic), they contain spaces around them and this is triggering the MD037 rule:

This is the text. The highlighted part is not in italic, but the linter is throwing an error:

format, and it must have both, private key and certificate (the *.pem file created must contain a 'CERTIFICATE' section as well as a 'RSA PRIVATE KEY' section). The *.pem file can be created using cp server.crt server.pem

The same happens here, between the 2 _esni (lines 69 and 78).

Maybe we need to escape asterisks and underscores, or just disable rule MD037 for the file.

Already identified and fixed - see latest commit :)

The current code will fail tests until we merge #1263.

We need to wait to merge this until the FTL code that generates/updates this PR is on master.

Should we add a comment on top if this file that it should not changes directly in this repo, but over at FTL?
