chore: upgrade Prettier and ESLint

[arnautov-anton]

Description of the changes, What, Why and How?

• upgraded Prettier to latest available version, adjusted configuration
• upgraded ESLint to latest available version, added new configuration
• dropped unused packages:
  • commitlint stuff (@commitlint/cli, @commitlint/config-conventional)
  • ESLint plugins (eslint-config-prettier, eslint-plugin-markdown, eslint-plugin-prettier, eslint-plugin-sonarjs, eslint-plugin-typescript-sort-keys)
  • standard-version - deprecated (previously used for versioning and CHANGELOG.md generation)
  • replaced @typescript-eslint/eslint-plugin & @typescript-eslint/parser with typescript-eslint
• commit linting now happens through separate CI job (pr-check.yml)

Notable Changes:

• added GITHUB_TOKEN for @semantic-release/github - use different @stream-ci-bot instead of @semantic-release-bot (1c313e8)
• as part of this PR I've decided to migrate Mocha-based tests to Vitest, see here
