Dependency conflict with `myst-parser`

[devmcp]

Describe the bug

When I add mdformat-myst to my Poetry environment it downgrades myst-parser to an extremely early and pretty much unusable version (0.7.1). I think this is because of the restriction on mdit-py-plugins:

"mdit-py-plugins >=0.3.0,<0.4.0",

Is the restriction to < 0.4.0 necessary?

Reproduce the bug

In a poetry environment (or presumably using any other dependency management tool) add md-format and myst-parser to the environment.

I confirm the issue between the last 2 release of mdformat-myst and mdformat-admon:

INFO: pip is looking at multiple versions of mdformat-admon to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install mdformat-admon==1.0.2 and mdformat-myst==0.1.4 because these package versions have conflicting dependencies.

The conflict is caused by:
    mdformat-myst 0.1.4 depends on mdit-py-plugins<0.3.0 and >=0.2.7
    mdformat-admon 1.0.2 depends on mdit-py-plugins>=0.4.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

@hukkin : Are you on this? Is the fix by @kdeldycke working?
I had to uninstall mdformat-myst now, which means probably having to uninstall mdformat soon-ish. When forced to choose, we prefer using myst-parser 2.0 (instead 1.0) over using mdformat.
