Problem: Missing node version requirement

[anvit]

Neither the installation manual nor the BS5 themeing page mention which version of node is required by AtoM.

In https://www.accesstomemory.org/en/docs/2.8/admin-manual/installation/ubuntu/#compile-bootstrap-5-theme-files or https://www.accesstomemory.org/en/docs/2.8/admin-manual/customization/theming/#custom-bootstrap-5-theme pages should mention which version of node is required by the current AtoM version (Node v18 or above for AtoM 2.8)
