Fix: Increase LaTeX memory limits in GitHub workflow

The GitHub workflow was failing to compile the PDF due to exceeding TeX's memory capacity. This commit increases the memory limits for `main_memory` and `pool_size` in the `texmf.cnf` configuration file to resolve this issue.

The `fmtutil-sys --all` command is used to rebuild the LaTeX format files with the new memory settings. This ensures that the changes are applied correctly during the PDF compilation process.

This fix addresses the "TeX capacity exceeded" error and enables the workflow to successfully generate the PDF output.
