Relax the validation of versions for npm packages

Context

When $ npm publish does auto-corrections, it can cause failures when uploading npm packages to a GitLab NPM registry. To solve this, users should:

• $ npm pkg fix which will simply apply the auto corrections
• Commit the changes to package.json (This could be optional, but it avoids running step 1 all the time.)
• Run $ npm publish
• This time around, it will not auto-correct things (since they are already auto-corrected). The upload will be accepted.

Problem to solve

Relax the validation checks for versions to reduce the number of failed npm uploads.

⚙ Technical details

Use https://gitlab.com/gitlab-org/ruby/gems/semver_dialects (already included in the GitLab codebase) to do version comparisons in a less strict manner.

This way, the same parts that $ npm ignores will be handled.

Example:

v = SemverDialects.parse_version("npm", "1.0.0+a")
v.to_s
=> "1.0.0"

v = SemverDialects.parse_version("npm", "v1.0.0")
v.to_s
=> "1.0.0"

v1 = SemverDialects.parse_version("npm", "v1.0.0+a")
v2 = SemverDialects.parse_version("npm", "1.0.0")

v1 == v2
=> true
