Fix boolean parameter handling in explorer-alpha command

Problem

When running the dcl start command with boolean flags like --landscape-terrain-enabled without providing a value, the command would fail. This happened because the code was treating these parameters as strings and trying to convert them to booleans, but when no value was provided, the conversion would fail.

And the creator-hub sometimes use that flag without a value so some users where having issues to preview their scenes.

Example of the failing command:

npm start -- --explorer-alpha --landscape-terrain-enabled
