Use markdownlint instead of mdlint

[unjust]

Devs not using linux/unix based OS have had problems with mdlint

Propose the use of https://github.com/DavidAnson/markdownlint/ which is more maintained.

• Has VSC extension
• node CLI https://github.com/DavidAnson/markdownlint/?tab=readme-ov-file#related

We can start with a basic config, install the node cli in the project, and run the gh action. Need to confirm with wiindows users that this works .https://github.com/DavidAnson/markdownlint/blob/v0.33.0/schema/.markdownlint.jsonc
