refactor: use `os.ReadDir` for lightweight directory reading

bump version to v3.8.0

`os.ReadDir` was added in Go 1.16 as part of the deprecation of `ioutil`
package. It is a more efficient implementation than `ioutil.ReadDir` as
stated here https://pkg.go.dev/io/ioutil#ReadDir

Fix panic with OCI for install, upgrade, and show

When range support for OCI went in via #10527 it created a situation
where some lookups for a chart could cause a panic. This change
makes sure the registry client is available to lookup OCI charts

Largely borrowed from (IndexFile).Get. However there is not currently a nice
way to make this code also usable to the repo package, as IndexFile depends on
a list of index Entries containing a nexted version.

We could refactor this later to somehow use the same shared function, but for
now keeping separate.
