build: remove semantic-release dependency

[mohanraj-r]

• semantic-release was added as a dependency recently to publish a github release
  • but couldn't get it to work as desired
• it brings in a huge list of dependencies and non-trivial learning curve
• it is not mono-repo aware/friendly
• when lerna is used for versioning and publishing, semantic-release doesn't offer a whole lot over it
• the github release notes needs to be hand-edited from the changelog anyways
