Error: command error: failed to load modules: module "github.com/gohugoio/hugo-mod-bootstrap-scss/v5" not found in "C:\AHUGOWEB\priyanshupapers\themes\github.com\gohugoio\hugo-mod-bootstrap-scss\v5"; either add it as a Hugo Module or store it in "C:\AHUGOWEB\priyanshupapers\themes".: module does not exist

for [[module.imports]]
path = "github.com/gohugoio/hugo-mod-bootstrap-scss/v5"
disable = false
