Remove build reliance on .git (#481)

fixes #477 

**Description :**

This pull request addresses the issue where the build process was
relying on Git for version information. The problem arose when the build
process did not have Git available.

**Changes Made :**

-In package.json, updated the `version` field to the latest released
GitHub version

-In build.ts, modified the code to use the version specified in
package.json.
