UpdatePaths: Handle lists containing strings (#62595)

* UpdatePaths: Handle lists containing strings

The split_re regex considers two alternatives when splitting out property
values.
The first alternative, "(?:.+?)" looks for a value that starts and
ends with a double quote, containing any characters between, but using
the smallest length possible.
The second alternative, [^";]* looks for a value that does not contain
any double quotes or semicolons.

Neither of these cases will handle a value such as network = list("fsc");

To handle this case without a major rewrite, the second alternative is
updated to [^"][^;]+ which looks for a value that does not start with a
double quote and does not contain a semicolon.

* UpdatePaths Support @OLD;... too

This strips the trailing semicolon, if present, which it will be if
you're overriding an old value after specifying @OLD.

* UpdatePaths: Handle single char case
