Validate 'redocly/cli` package before publishing to npm and workflows

[SmoliyY]

Description

redocly/cli release 1.0.0-beta101 was failed due to publishing code that use package that do not exist in packages/cli/package.json, but instead this package exist in root package.json. Also we need to add test to check workflows functionality

Solution

• Add check (e.g eslint rule) that would check if package exist in packages/cli/package.json
• Add test that would build same packages that published to npm
• Add more tests for workflows functionality

Turns out npm pack from here doesn't include the corresponding openapi-core what leads to inconsistency in this test. I'm reopening this issue as I had to comment out this job and this should be fixed.
