feat: add mparticle to launcher integration name

[alexs-mparticle]

Summary

I've improved the version referencing in the mParticle-Rokt integration by:

• Adding the rollup/plugin-replace plugin to properly inject the package version at build time
• Updated the rollup configuration to get actual version from package.json
• Modified the string concatenation syntax in initialization.js
• These changes ensure that the integration properly identifies itself with its version number when creating the Rokt launcher, allowing for better tracking and debugging of integration versions in production.

Restores #16

Testing Plan

This has been tested by:

• Verifying the syntax is valid JavaScript that works in all browser environments
• Confirming the rollup configuration correctly imports and uses the package.json version
