Improvements from TR1 and TR2 testing

BunchGroup fixes (ATR-20810):

• New successful read printout
• Removed reading RunParams, but until ATLAS in use reading current key not confirmed to work (but warning improved)
• Two typos corrected
• cc @aporeba

AutoPrescaler updates (ATR-25935)

• To avoid duplication of keys, AP generated keys will no longer have "AUTO_" in the name parameter inside the JSON file
• The insertPrescales script will append this to the table entry so in TTweb and TriggerPanel the name will appear still with "AUTO_"
• cc @aporeba @shanisch @dzanzi

MonGroups

• fix typo in self.MonitoringGropIsDuplicate which affected the uploadrecord information
• Change printouts "In Use = 1." to "In Use = True"
• Improved code search-ability/read-ability by making it clearer where a variable refers to the key rather than the filename

InsertMenu

• Unified the printout with all the other uploads "Please use the existing configuration" -> "Using existing entry"
