myst-docutils-html doesn't appear to accept the myst configuration parameters or directives

Describe the bug

context When I do myst-docutils-html --myst-enable-extensions="html-image,colon-fence" test.md test.html

expectation I expected the HTML file to be created without any errors.

bug But instead I get an error

myst-docutils-html --myst-enable-extensions="html-image,colon-fence" test.md test.html
test.md:: (ERROR/3) myst configuration invalid: myst_enable_extensions not recognised: {'colon-fence', 'html-image'}
test.md:38: (ERROR/3) Unknown directive type "seealso".

test.md:27: (ERROR/3) Unknown target name: "../solution_components/platform-tcp.md".
test.md:30: (ERROR/3) Unknown target name: "#21-use-cases".

The original test.md file is:

This is a problem as it appears that the MyST directives aren’t accepted by this utility, and the command line options don’t accept valid MyST extensions.

Reproduce the bug

test.md containing:

Then run the following command: myst-docutils-html --myst-enable-extensions="html-image,colon-fence" test.md test.html

Hey, @tomkivlin there are two things to note here:

1. It should be "html_image,colon_fence", i.e. _ not -
2. The seealso directive is sphinx only, i.e. it is not supported by docutils and so cannot be parsed by myst-docutils

[tomkivlin]

so am I right in thinking the admonitions listed here are ok to use with both MyST in sphinx and with myst-docutils?

yep 👍

Many thanks - am closing the issue as modifying the admonition and using the following command works: myst-docutils-html --myst-enable-extensions="html_image,colon_fence" --myst-all-links-external="yes" test.md test.html
