Description
When a configuration Map which has an entry with a key "someKey" and a value "${file:/F:/properties.txt:fileKey}" is passed to the ConfigTransformer.transform(Map) method, an exception is thrown:
2022-08-12 16:44:21,553 ERROR [org.apa.kaf.com.con.pro.FileConfigProvider] (main) Could not read properties from file /F: java.nio.file.NoSuchFileException: \F

This happens because of a colon ":" in the file name, which is wrongfully matched by the ConfigTransformer.DEFAULT_PATTERN in these three groups "file", "/F" and "/properties.txt:fileKey" instead of "file", "/F:/properties.txt" and "fileKey".
The ConfigTransformer.DEFAULT_PATTERN should be changed to match the first and the last colon ":" in the expression.
