Update renames for ITV1

[orryverducci]

This updates the renames on the Sky UK and Freesat EPG's for ITV1 as follows:

• ITV renamed to ITV1 (channel was rebranded in November 2022)
• SD and +1 regions no longer being broadcast on satellite have been removed
• Region names have been standardised so they're the same on both platforms
• 'Westcountry' changed to 'West Country' to reflect the name as now used by ITV

Ideally, Sky Ireland needs to be changed to match too.

Excellent. Thank you, both of you.
