fix(ci): build static native binary (musl) to fix glibc version mismatch

Container `maven:3.9.6-eclipse-temurin-21` is Ubuntu 22.04 jammy
with glibc 2.35. Container `quarkus-micro-image:2.0` is UBI 9
minimal with glibc 2.34. Native-image links against the build
host's glibc, so the resulting binary needs GLIBC_2.34+ symbols
that the UBI 9 runtime doesn't provide:

  ./application: /lib64/libc.so.6: version `GLIBC_2.34' not found
  ./application: /lib64/libc.so.6: version `GLIBC_2.33' not found
  ./application: /lib64/libc.so.6: version `GLIBC_2.32' not found

Set quarkus.native.binary-type=STATIC so GraalVM embeds musl into
the binary and removes the glibc dependency. The static binary
runs on any Linux distribution, including UBI minimal. Trade-off:
~50MB -> ~80MB image size.
