suggestion: `pedantic` tag for opinionated rules

[0f-0b]

Clippy has a pedantic lint group that contains opinionated but still generally useful lints. I suggest adding a similar rule tag to deno lint, covering rules such as camelcase, eqeqeq, no-throw-literal, no-useless-rename, require-await and verbatim-module-syntax.
