feat: Add a script to manage version updates

[jayan-blutui]

This PR introduces a script update-version to handle SDK versioning. Running the update-version npm script will automatically apply a change to the appropriate files based on the desired version.

For example the following script will update the appropriate files to create a patch. Version 1.0.0 would become 1.0.1:

npm run update-version -- --patch

Similarly adding the --minor argument would update the version from 1.0.0 to 1.1.0:

npm run update-version -- --minor

For a major release, adding the --major argument would update the version from 1.0.0 to 2.0.0:

npm run update-version -- --major
