Fix dockerfile to include glibc for runtime dependency

[Mayon-Francis]

Description

For compatibility with glibc, some options that were attempted, but didn't work out were:

# apk add gcompat
# apk add libc6-compat

They both resulted in errors similar to the one shown below with alpine-glibc-v2.35-r0

This patch installs glibc for alpine to include the C Runtime Dependencies.

The version chosen is 2.34-r0 instead of 2.35-r0 (Latest Release). This is because the latest release is producing errors at runtime as follows:

Error relocating /lib/ld-linux-x86-64.so.2: unsupported relocation type 37
Error relocating /bin/parseable: __memcpy_chk: symbol not found
Error relocating /bin/parseable: __register_atfork: symbol not found
Error relocating /bin/parseable: gnu_get_libc_version: symbol not found
Error relocating /bin/parseable: __res_init: symbol not found

• Added Glibc package
• Added a chown (missing folder permission for parseable user

This cannot be merged yet as the server panics with the following error upon starting
