Bump image version in Dockerfile

[salmonek]

Description

JIRA: https://tiugotech.atlassian.net/jira/software/c/projects/UCLIBS/issues?jql=project%20%3D%20UCLIBS%20ORDER%20BY%20created%20DESC&selectedIssue=UCLIBS-685

Updating an image version in the Dockerfile should remove most warnings in the report. It looks like I cannot verify this locally as PHPStorm's Snyk plugin shows only issues in the source code.

This PR doesn't affect any actual library file

🧹 Recent nitpick comments

Dockerfile (1)

4-5: Consider consolidating apk commands to reduce image layers.

The linux-headers addition is correct—it's required for compiling xdebug on newer Alpine/PHP versions. For minor optimization, you could combine these into a single layer with consistent flags.

♻️ Optional: Consolidate apk commands

-RUN apk add --update linux-headers
-RUN apk add --no-cache git
+RUN apk add --no-cache linux-headers git

2-2: No concerns with this update.

The uploadcare-php library already declares PHP 8.x support in composer.json (constraint: >=7.4 || >=8.0) and runs CI tests on PHP 8.0 and 8.4, confirming compatibility across the 8.x range. The codebase uses modern tooling (rector, psalm, php-cs-fixer) that prevents deprecated patterns. The Dockerfile upgrade to PHP 8.3-fpm-alpine is well-supported and safe.
