• Updated the CHANGELOG to document the fix.
• Modified tasks/modules/install-modules.yml to use nginx_version as the default value in module installation.
• Adjusted molecule tests by removing version fields for geoip and perl modules where versioning is no longer supported.

tasks/modules/install-modules.yml:31

• [nitpick] The default filter expression is rather complex; consider refactoring it for clarity, for example by using '{{ item['version'] | default(nginx_version | default('')) }}'.

{{ item['version'] | default((nginx_version is defined) | ternary(nginx_version, '')) }}

molecule/version/converge.yml:38

• The removal of the version field for the geoip module appears intended; please confirm this change aligns with the module’s behavior regarding version support.

version: "{{ ngx_version }}"

molecule/version/converge.yml:44

• The removal of the version field for the perl module is appropriate if versioning is not supported; please verify that this behavior is expected.

version: "{{ ngx_version }}"
