Update nodejs installation method in release container (go-gitea#27207) (go-gitea#27212)

Backport go-gitea#27207 by @silverwind

Nodesource has
[deprecated](https://github.com/nodesource/distributions#new-update-%EF%B8%8F)
their install script, so use this new [manual
method](https://github.com/nodesource/distributions#installation-instructions)
instead.
