Support wildcard in the 'include' property of the rpa.json

Current behavior
`"include": ["Assistant_Thanks.wal", "Assistant_OrangeHRM.wal"]`

New behavior
`"include": ["Assistant_*.wal"]`

Remember to exclude the **main file** - the robot. For example, if the robot is `Assistant` and the include is `Assistant*`, then the `Assistant.wal` file should not be included.
