Update Semver package to use WP GraphQL Semver library

[colinmurphy]

In order to resolve #350 and reduce maintenance burden, we should replace the current Semver package and use WP GraphQL Core.

Acceptance Criteria

• [ ] Upstream WPGraphQL semver library is able to be utilized by 3rd party plugins
• [ ] WPGraphQL can be updated from 1.x to 2.x without deactivating wp-graphql-content-blocks

Notes

This may need some work on WPGraphQL side to expose some options in order for WPGraphQL Content Blocks to use this. See https://github.com/wpengine/wp-graphql-content-blocks/issues/350#issuecomment-2665943675
