Error in description of the property column.mask.hash._hashAlgorithm_.with.salt._salt_

The following sentence in the description for the property column.mask.hash.hashAlgorithm.with.salt.salt is incorrect:

Multiple properties with different lengths can be used in a single configuration, although in each the length must be a positive integer or zero.

This error exists in in the documentation for the following connectors:

• MySQL
• SQL Server
• Oracle (Fixed as part of DBZ-3407)

The errors appears to result from overzealous copy-/pasting from a sentence in the description for the property column.truncate.to.length.chars.

The masking property specifies a hashing algorithm and a salt, but not a length.

Modify the sentence so that it reads as follows:

The connector configuration can include multiple properties that specify different hash algorithms and salts.

In addition, the description of the property is inconsistent across the different connectors, even in the docs that don't include the error (PostgreSQL, Db2). Rewrite for consistency across the docs.
