tools: add remark-lint configuration in .remarkrc

Specifies the configuration for remark-lint, a markdown linter.

This configuration does not cause any warnings on any of the currently
present *.md files (ignoring thirdparty).

It is useful not only for possible future tooling that would check the
markdown files syntax, but also as a configuration for editor plugins,
e.g. linter-markdown for atom-linter.
