chore(refactor): use uppercase imports for class-like modules only

## Details

Changes the following "imports" to lowercase:

- `render-markdown.lib.compat`
- `render-markdown.lib.converter`
- `render-markdown.lib.env`
- `render-markdown.lib.icons`
- `render-markdown.lib.iter`
- `render-markdown.lib.list`
- `render-markdown.lib.str`
