Fix Out-of-bounds Read in folio-ansible stripes Dockerfile

nginx:stable-alpine in https://github.com/folio-org/folio-ansible/blob/master/roles/stripes-docker/templates/Dockerfile.j2 contains

pcre2/pcre2@10.39-r0

that has Out-of-bounds Read vulnerabilities:

• https://nvd.nist.gov/vuln/detail/CVE-2022-1586
• https://nvd.nist.gov/vuln/detail/CVE-2022-1587

A fix is available:

pcre2/pcre2@10.40-r0

However, nginx:stable-alpine doesn't immediately get security fixes: https://github.com/nginxinc/docker-nginx/issues/671

Therefore RUN apk --no-cache upgrade is needed.
