Strip markdown from parameter placeholder

Describe the bug

Have a parameter defined for some path.
That parameter can have a description which according to the OAS spec supports CommonMark syntax.

This description is used by packages/docusaurus-theme-openapi-docs/src/theme/ApiExplorer/ParamOptions/ParamFormItems/ParamTextFormItem.tsx (and ParamArrayFormItem.tsx) as placeholder on the <FormTextInput>.

This would show raw markdown if description contains markdown (e.g. a raw markdown link such as leading [Some link](/pointing/somewhere) trailing.

Expected behavior

Strip the markdown to plaintext so the placeholder text is readable. The correctly rendered markdown is anyways in the main section.

So leading [Some link](/pointing/somewhere) trailing should become leading Some link trailing.

Current behavior

Raw markdown is rendered as text.

Possible solution

Maybe use something like https://github.com/remarkjs/strip-markdown to strip non markdown elements.
