ci(eslint): update @typescript-eslint from 3.10.1 to 4.22.0

We need to update @typescript-eslint from 3.10.1 to 4.22.0 as !189 (merged) upgraded TypeScript from 3.x to 4.x.

We need to make it off in the two base rules: no-shadow and no-use-before-define to utilize @typescript-eslint/no-shadow and @typescript-eslint/no-use-before-define. Otherwise we will see the errors shown at https://gitlab.com/gitlab-org/gitlab-vscode-extension/-/jobs/1228622149

• https://github.com/typescript-eslint/typescript-eslint/blob/v4.22.0/packages/eslint-plugin/docs/rules/no-shadow.md
• https://github.com/typescript-eslint/typescript-eslint/blob/v4.22.0/packages/eslint-plugin/docs/rules/no-use-before-define.md
