feat(package.json): Add lint yarn script + make it a precondition to build all packages.

fmt(tiptap-commands): Fix all ESLint violations with `--fix`

fmt(tiptap-commands): Ignore some ESLint rules on code copied from prosemirror.

fmt(tiptap): Apply ESLint autofix to `tiptap` package sources.

fmt(tiptap-extensions): Fix ESlint violations from `marks`

refactor(tiptap-extensions): Fix ESLint violations for `plugins/Suggestions.js`.

Some of the violations required a bit of restructuring of the code/logic

fmt(tiptap-utils): Fix ESLint violations.

feat(package.json): Add yarn script to lint source code before compiling the examples.
