There is actually a docs build failure on GHA from this line:

One option would be to escape the backticks like \`. But, it's even better
to just drop the inline single and double backtick examples given that you
have an example block below which shows both. So, keep the bulleted
descriptions, but remove the examples in parenthesis.
