This commit extracts the information about the configuration the user should do right after installation (especially running scylla_setup) to a separate file. The file is included in the relevant pages, i.e., installing with packages and installing with Web Installer. In addition, the examples on the Web Installer page are updated with supported versions of ScyllaDB. Fixes https://github.com/scylladb/scylladb/issues/19908 Closes scylladb/scylladb#20035
