Remove the Upper Mass Cut on HNL T Track Combiners

This simple merge request reflects a small change in the tuning of the T track HNL lines to remove the high-mass cut on the HNL mass.

This is done to have an upper mass sideband for HNL and other analyses.

The bandwidth impact over 100,000 events following the QEE testing framework is small and only measurable for the Hlt2QEE_N_EMuNu_SS_inclTT line, where the difference is + 2 MB/s:

Line	Reference Rate (kHz)	Reference Total Bandwidth (GB/s)	Comparison Rate (kHz)	Comparison Total Bandwidth (GB/s)	Difference in Rate (kHz)	Difference in Total Bandwidth (GB/s)
Hlt2QEE_N_EMuNu_SS_inclTTDecision	0	0	0.0258	0.00215813	0.0258	0.00215813
