Recma plugins order

[pomber]

#2866 added support for recma plugins, but they are being applied after nextra custom plugins: https://github.com/shuding/nextra/pull/2866/files#diff-529083ef03cb653fd91399220a1a136114d36a4b6fed51cef498562c26a1ac7fR349

User's remark and rehype plugins are applied before any nextra plugin, maybe it will be more consistent if the same applies to recma.

(not a nitpick, this is breaking the integration with Code Hike)

I can send a PR if needed

[dimaMachina]

hey, do you still need this feature?

[pomber]

Yes!

(In the meanwhile, I've been using patch-package to change the order so it works with codehike, but it's far from ideal)
