Use distroless/static image instead of distroless/base since glibc is not used

[vilmosmartinek]

What problem are you facing?

This template is using distroless/base-debian as its base image (see here), even though it is quite explicitly not using glibc:

# Most functions don't want or need CGo support, so we disable it.
ENV CGO_ENABLED=0

The documentation of distroless says the following:

Statically compiled applications (Go) that do not require libc can use the gcr.io/distroless/static image, [...]
[...]
Most other applications (and Go apps that require libc/cgo) should start with gcr.io/distroless/base, [...]

How could this Function help solve your problem?

It would make sense to change the base image to gcr.io/distroless/static, allowing smaller and safer images.
