tools: update remark configuration

Specify the plugin name as 'remark-lint/', as new remark-cli refused to
find it when cwd is different from the directory where node_modules are
put. Trailing slash fixes this, as the plugin name gets treated as a
path, so `require` works on it.

Explicitly specify the list of rules we want to enable, as the new
remark-lint is opt-in and doesn't come with any rules by default.

Reorder the rules alphabetically.
