Pull request overview

Updates the AWS Lambda container example to illustrate how to install the SolarWinds OpenTelemetry Collector Lambda extension for different container architectures (x86_64 vs arm64).

Changes:

• Added a README note prompting users to select platform-appropriate Dockerfile commands for extension installation.
• Added Dockerfile instructions intended to show both x86_64 and arm64 extension installation options.

• This Dockerfile currently installs both the x86_64 and ARM64 collector extensions (and re-declares the same ARG names). That means an x86_64 build would end up overwriting the x86_64 extension with the ARM64 one (broken at runtime), and an ARM64 build does unnecessary extra download/work. Make the non-target architecture block non-executable (or switch to a TARGETARCH-based conditional).
