Docs: Corrections to Arkane's Multidimensional Hindered Rotors docs

Without an empty line between a text block and a table block, the table won't be auto-formatted. Also deleted a leading space in the text that Sphinx complained about. Also a table's header/bottom was fixed.

 Multidimensional Hindered Rotors

-For multidimensional hindered rotors, ``geometry``, ``frequencies`` need to be specified in the same way described in detail in the last section. However,
-rotor files may be specified by either a 1D rotor scan file as in the last section (1D rotors only) or as a directory.

 The inputs are mostly the same as the last section except that HinderedRotorClassicalND takes lists of pivots,
 tops and sigmas instead of individual values. These rotor objects enable calculation of partition functions for 
-multidimensional torsions that are particularly important for QOOH molecules and molecules involving intramolecular hydrogen 
-bonding. It is worth noting that HinderedRotor2D can take on the order of hours to run. To mitigate this the 
-.evals file in the directories Q2DTor directories are searched for automatically and used if present to reduce runtime to seconds. 
-This means if you have run a system with HinderedRotor2D and wish to rerun the system and recalculate the HinderedRotor2D
- you should delete the .evals file. HinderedRotorClassicalND usually runs quickly for lower dimensional torsions.
