fix(docs): correct the target specific macros for secure boot v2 guide
It appears that target specific or'ing is not supported through the
docs build. Actual text rendering on the docs site was still using
"default" field from the custom macro, rather than using target
specific.

2c3c4adaa3 docs(docker): Update Using Remote Serial Port chapter
By default some shells such as zsh has NOMATCH option set (https://zsh.sourceforge.io/Doc/Release/Options.html).
The root cause of the problem is that while bash expands the parameter to itself if it does not match any filename, the zsh reports an error. IOW if we do % setopt nonomatch it will work even in zsh.
