Add missing parameter aliases to align with caller/callee

[kyllath]

Fix issue where none of 'HeaderRow', 'TopRow' and 'StartRow' work in ConvertFrom-ExcelToSQLInsert, preventing you from skipping rows.

Issue is that aliases are missing from the parameter list of ConvertFrom-ExcelData.
ConvertFrom-ExcelToSQLInsert accepts 'HeaderRow', 'TopRow' and 'StartRow', but passes 'StartRow', while ConvertFrom-ExcelData only accepts 'HeaderRow'

FIX: Alter ConvertFrom-ExcelData to have the same aliases for the parameter as both its caller, ConvertFrom-ExcelToSQLInsert and its callee, Import-Excel. All three now have:
[Alias('HeaderRow', 'TopRow')]
[Int]$StartRow = 1,

Hmm. Feels like TopRow should be added as a param not an alias. It's been a long time since I've benn in this part of the code.

The reason I chose this approach is that ConvertFrom-ExcelToSQLInsert always calls ConvertFrom-ExcelData, which in turn calls Import-Excel. Both ConvertFrom-ExcelToSQLInsert and Import-Excel have StartRow as the param with HeaderRow and TopRow as aliases, so this way just makes all three consistent with the minimum of changes.
