path to shape in output is inside ESMValTool output directory, but shapefile is not

[RolfHut]

typical output of generating forcing looks like:

MarrmotForcing(
    start_time='1990-01-01T00:00:00Z',
    end_time='1990-12-31T00:00:00Z',
    directory=PosixPath('/home/rhut/repos/technicalPaperExampleNotebooks/esmvaltool_output/ewcrep0na0ttkf_20250419_
081350/work/diagnostic/script'),
    shape=PosixPath('/home/rhut/repos/technicalPaperExampleNotebooks/esmvaltool_output/ewcrep0na0ttkf_20250419_0813
50/work/diagnostic/script/settingFiles/Merrimack.shp'),
    filenames={},
    forcing_file='marrmot_ERA5_Merrimack_1990_1990.mat'
)

where the output folder is pasted before the shape path, but this is incorrect since the shape file is not copied to that location.

prefered fix: copy shape file to that location to have everything packaged together in one location.
