yarn v1 fails at sometimes.
#988 (comment)
We have used cache, but yarn fail to fetch

textlint/.github/workflows/ci.yml

Line 20 in ca4fda9

cache: 'yarn'

Yarn v1 will not fix these issues.

• CLI functionality related to aggregator preventing yarn commands 1.19-1.22 - Reverted to 1.16 yarnpkg/yarn#7734
• Yarn fails with ESOCKETTIMEDOUT while installing a large package on a slow disk yarnpkg/yarn#8242

We can move to npm 8+. Now is the time.

TODO

• remove yarn.lock
• add package-lock.json
• change lerna.json to npm

  • textlint/lerna.json

    Lines 3 to 6 in ca4fda9

    	"npmClient": "yarn",
    	"useWorkspaces": true,
    	"packages": ["packages/*", "examples/*", "packages/@textlint/*", "test/integration-test", "website"],
    	"includeMergedTags": true,

• Replace yarn to npm command in CI and scripts ant netlify.yml etc...
• Rewrite CONTRIBUTING.md

Test Plans

• Pass CI
• grep yarn
  • rg is useful
