[Feature Request]: Inside a pipeline that is referenced by "Pipeline executed to capture logging" path variables are displayed incorrectly; plus minor issues

### What would you like to happen?

Migration: https://issues.apache.org/jira/browse/HOP-4094

**Issue I (main issue):**
In a project that uses workflow and pipeline logging, we have a pipeline referenced by "Pipeline executed to capture logging" ("logging_a_pipeline.hpl" in "logging"-subfolder) inside the Metadata object "Pipeline_Log".

The "Pipeline_Log" captures the output of "produce_data.hpl" in "sub"-subfolder.

The pipeline "logging_a_pipeline.hpl" uses two "Text file input" transforms whose paths use variables ("${Internal.Entry.Current.Folder}" or "${Internal.Pipeline.Filename.Directory}", the problem is the same for both).

The tooltip on the paths in the "Text file input" transforms does NOT show the path that is actually produced when the project runs, and is therefore incorrect (or, at least, very misleading).

The exact symptom is that during execution of the project the variables actually hold the path to "sub" folder that contains "produce_data.hpl", but not (as one would expect and what the tooltip shows!) the path to the "logging" folder that contains "logging_a_pipeline.hpl".

How to reproduce:

simply start "main.hwf", and then experiment with the paths in the "Text file input" transforms in "logging_a_pipeline.hpl".

**Issue II (minor):**
The documentation on the checkbox "Logging parent pipelines only" in https://hop.apache.org/manual/latest/metadata-types/pipeline-log.html is missing.

I was quite confused about the semantic, but what I think I could find out is, that in case the checkbox is checked, the log is ONLY produced if the pipeline is started directly. Is that correct?

https://hop.apache.org/manual/latest/metadata-types/workflow-log.html

**Issue III (minor):**
The paths under "Capture output of the following pipelines" can use variables (here: "${PROJECT_HOME}", but are

missing the blue diamond symbol which is normally present
CTRL+SPACE does not work
Issue IV (minor):
The path in "Pipeline executed to capture logging" does not accept CTRL+V

### Issue Priority

Priority: 3

### Issue Component

Component: Documentation, Component: Hop Gui

Reproduce the behavior by starting main.hwf and inspecting logging_a_pipeline.hpl, produce_data.hpl, and the Pipeline_Log metadata object, especially the Text file input paths. Compare the displayed tooltips with the runtime paths, then review the pipeline-log documentation and the controls for variable assistance and paste support. Done means the reported path, documentation, autocomplete, and paste issues are verified and addressed.
