Review eslint config (#3269)

- Remove "prettier" from plugin array, because it's already enabled by
"plugin:prettier/recommended"
- Remove "jsdoc" from plugin array, because it's already enabled by
"plugin:jsdoc/recommended"
- Enable recommended import rules
- Add two additional import rules

Note: To avoid overloading this PR I'll tackle the jest part with
another PR after this one has been dealt with.
