Subject: modules: no --delim option if separator is colon character (#39010)

Update Tcl modulefile template to simplify generated `append-path`,
`prepend-path` and `remove-path` commands and improve their readability.

If path element delimiter is colon character, do not set the `--delim`
option as it is the default delimiter value.
