[Breaking Change] string WhereX methods should not use the LOWER method by default

[ahmad-moussawi]

Currently SqlKata will try to apply a case insensitive operation, for WhereString operations,
for example this query

var query = new Query("Car").WhereLike("Name", "AM");

will get translated to

SELECT * FROM [Car] WHERE LOWER([Name]) like 'am'

What requested is to keep the default behavior of the database, and only apply the transformation if explicitly needed

Acceptance Criteria:

• The default value for the caseSensitive for WhereLike, WhereStarts, WhereEnds should be true instead of false
• The documentation should be updated to reflect this change

I agree with @ahmad-moussawi. Also, calling LOWER on every parameter has a significant performance overhead.
