markdown linting

[ccozens]

I want to ensure consistent markdown formatting to reduce the chances of issues rendering md files. So, given I'm already using an mdsvex remark plugin, remark-lint looks good. From a quick skim, options I might include are:

• remark-lint-fenced-code-flag
• remark-lint-fenced-code-marker
• remark-lint-no-consecutive-blank-lines
• remark-lint-no-empty-url
• remark-lint-no-missing-blank-lines
• remark-lint-frontmatter-schema
• remark-lint-fenced-code-flag-case

There may be overlap here. The main one is the frontmatter schema. Code language also a big bonus.
