[I] [Bug]: Pipeline executor log shows "Unable to load pipeline [{0}]" instead of the file name (hop)

Adalennis opened a new issue, #9019:
URL: https://github.com/apache/hop/issues/9019

   ### Apache Hop version?
   
   2.20.0-SNAPSHOT
   
   ### Java version?
   
   Java 21
   
   ### Operating system
   
   macOS
   
   ### What happened?
   
   When the Pipeline executor can't load its sub-pipeline, the log shows the message placeholder instead of the file name:
   
       Unable to load pipeline [{0}] : can't find directory
   
   `TransformWithMappingMeta.loadMappingMeta()` (line 146) calls `BaseMessages.getString(PKG, "TransformWithMappingMeta.Exception.UnableToLoadPipeline")` without passing `realFilename`, so `{0}` is never filled in. The message also always says "can't find directory", whatever the real cause is (here the file doesn't exist).
   
   To reproduce:
   1. Create a pipeline with Generate rows (1 row) → Pipeline executor.
   2. Set the Pipeline executor filename to `${PROJECT_HOME}/does-not-exist.hpl`.
   3. Run the pipeline and check the log.
   
   Expected: the message names the file, e.g. `Unable to load pipeline [/path/to/does-not-exist.hpl]`.
