Better error message when LaTeX compilations fail

[jl-marin]

If, for whatever reason, the compilation of the LaTeX report fails in create_pdf(), the error logged on the console is too vague about the location of the log file:

2025-02-03 20:41:29,567 |                  DGCV.PDFLatex |      ERROR |                 report.py:  484 | An error occurred while generating the report, log in report.log

Instead of simply saying "... log in report.log", it should include a hint to the location of this file under /tmp, such as for example, "... look for the report.log under /tmp/DGCV_Results//Reports/"_.

The error message is modified to include the location of the log file, for example:
An error occurred while generating the report, look for the report.log file under ../test/Reports
