sp_Blitz: update descriptions of Windows to remove "modern" wording for 2012

[BrentOzar]

Version of the script
SELECT @Version = '7.96', @VersionDate = '20200606';

What is the current behavior?
On a Win2012 R2 box, check 172 is reporting:

"You're running a pretty modern version of Windows: Server 2012R2 era, version 6.3"

What is the expected behavior?
We should remove the adjectives and just say the versions in this block:

								WHEN [ohi].[host_platform] = 'Linux' THEN 'You''re running the ' + CAST([ohi].[host_distribution] AS VARCHAR(35)) + ' distribution of ' + CAST([ohi].[host_platform] AS VARCHAR(35)) + ', version ' + CAST([ohi].[host_release] AS VARCHAR(5))
								WHEN [ohi].[host_platform] = 'Windows' AND [ohi].[host_release] = '5' THEN 'You''re running a really old version: Windows 2000, version ' + CAST([ohi].[host_release] AS VARCHAR(5))
								WHEN [ohi].[host_platform] = 'Windows' AND [ohi].[host_release] > '5' AND [ohi].[host_release] < '6' THEN 'You''re running a really old version: ' + CAST([ohi].[host_distribution] AS VARCHAR(50)) + ', version ' + CAST([ohi].[host_release] AS VARCHAR(5))
								WHEN [ohi].[host_platform] = 'Windows' AND [ohi].[host_release] >= '6' AND [ohi].[host_release] <= '6.1' THEN 'You''re running a pretty old version: Windows: ' + CAST([ohi].[host_distribution] AS VARCHAR(50)) + ', version ' + CAST([ohi].[host_release] AS VARCHAR(5))
								WHEN [ohi].[host_platform] = 'Windows' AND [ohi].[host_release] = '6.2' THEN 'You''re running a rather modern version of Windows: ' + CAST([ohi].[host_distribution] AS VARCHAR(50)) + ', version ' + CAST([ohi].[host_release] AS VARCHAR(5))
								WHEN [ohi].[host_platform] = 'Windows' AND [ohi].[host_release] = '6.3' THEN 'You''re running a pretty modern version of Windows: ' + CAST([ohi].[host_distribution] AS VARCHAR(50)) + ', version ' + CAST([ohi].[host_release] AS VARCHAR(5))
								WHEN [ohi].[host_platform] = 'Windows' AND [ohi].[host_release] > '6.3' THEN 'Hot dog! You''re living in the future! You''re running ' + CAST([ohi].[host_distribution] AS VARCHAR(50)) + ', version ' + CAST([ohi].[host_release] AS VARCHAR(5))
