Code Review

This pull request adds the git-delta package to the Docker image, which is a useful enhancement for viewing git diffs. However, the implementation is incomplete as it's missing the necessary Git configuration to automatically use delta as the pager. Additionally, a test case should be added to tests/specs.yaml to verify that git-delta is installed correctly by checking its version, which would maintain the test coverage for packages included in the image.

[gemini-code-assist]

While git-delta is being installed, it's not configured to be used by git automatically. To make this feature useful out-of-the-box, you should configure it as the default pager for git.

You could add this configuration in a subsequent RUN command, for example, by appending it to the command on lines 112-116:

RUN ln -s /usr/bin/eza /usr/local/bin/ls \
    && ln -s /usr/bin/batcat /usr/local/bin/bat \
    && ln -s /usr/bin/fdfind /usr/local/bin/fd \
    && ln -s "$(dirname "$(dirname "$(readlink -f "$(which java)")")")" "${JAVA_HOME}" \
    && git config --global core.pager delta

This will ensure that users of the image benefit from git-delta without needing manual configuration.

[Copilot]

The comment describes git-delta as a "Pager for git, diff, grep, and blame", but git-delta is primarily a syntax-highlighting pager for git, not for grep and blame. It's used to enhance git diff, git show, git log, and similar git commands. Consider updating the comment to be more accurate, such as "Syntax-highlighting pager for git diff and log".

Suggested change

	# Pager for git, diff, grep, and blame
