migrate to Alpine linux for primary container OS

[justinhauer]

Is your feature request related to a problem? Please describe.
No, but a lower surface area for CVEs.

Describe the solution you'd like
Stop using amazon linux and migrate to alpine linux, The amazon linux image is huge with far more than is necessary to run data prepper.

Describe alternatives you've considered (Optional)
I could build my own container and maintain a fork but this is not desirable

Additional context
This would potentially aid in the image starting faster, and lower the attack surface from a vulnerability perspective. There's a closed issue regarding this and it looked like someone had challenges building on ARM and they declined to build on alpine because of this.
