Wowchemy website doesnt update anymore

Dear all, I was using wowchemy to build my academic website. The last update was on January more or less. Yesterday, I wanted to update but I cannot change anything on it. This is my repository of interest : GitHub - serkankocabas/serkankocabas.github.io . I have this error most of the time : The following actions use a deprecated Node.js version and will be forced to run on node20: peaceiris/actions-hugo@v2, actions/cache@v3, actions/configure-pages@v3. For more info: GitHub Actions; All Actions will run on Node20 instead of Node16 by default - GitHub Changelog

I tried to update go.mod file and config file and netfily file as you said in the comments but it doesnt work and I am stuck. Would you help me with this?
Thanks in advance.
