Minicard component issues and features fixes

[timkim]

Minicard component has some css issues (errors and needs some features), adding text content as optional and also make the whole card as a link.

No semi-colon here:

aio-theme/packages/gatsby-theme-aio/src/components/MiniResourceCard/index.js

Line 67 in c293c01

height:80px

Results in the height not being set properly.

Text content should be option-able. This check will fail and throw an error if no text content is present:
https://github.com/adobe/aio-theme/blob/c293c01ac7340e498dacb6cb0716f8406638fb83/packages/gatsby-theme-aio/src/components/MiniResourceCard/index.js#L103C9-L103C9

The https://github.com/AdobeDocs/express-for-developers/ has a use-case of using the Minicard component without text body:
https://github.com/AdobeDocs/express-for-developers/blob/main/src/pages/index.md?plain=1#L80

The whole card should act as a link. May need another variant to support this as only the image is clickable.

Hi @timkim I've fixed the issue on the Minicard component. I checked with/without text now it's working fine.
This is the PR for that.
