Fix escaping of spaces in the classpath

[Shadow-Devil]

Purpose

If the path to the ballerina repo contains a space the build failed. This was fixed by changing the classPath of the :jballerina-tools:pathingJar to use .toURI() instead of .toURL(). This now escapes the spaces correctly with %20

Fixes #41090
