allow wget in elastic-dotnet-auto-install.sh

[codefromthecrypt]

This is the same fix as upstream here, which allows use of wget when curl isn't available, helpful on the runtime docker images. open-telemetry/opentelemetry-dotnet-instrumentation#4076

I tested it with a copy like below

wget and not curl

$ docker run --rm -it mcr.microsoft.com/dotnet/runtime:8.0-alpine
/ # sh -xc "$(wget -qO- https://gist.githubusercontent.com/codefromthecrypt/77865a27ad40dc4fa7ef35396a0ba4dc/raw/fa516690ee5afad5d53f1c4e7671a47a207b24d1/elastic-dotnet-auto-
