fix: add default keyword argument to kredis extension attributes

[dylanplayer]

Motivation

The arguments for many attributes in Tapioca::Dsl::Compilers::Extensions::Kredis are missing the default: keyword argument defined in the kredis gem here. This is causing the following error whenever you generate the DSLs for an application that uses the default: argument on a kredis attribute.

lib/tapioca/dsl/extensions/kredis.rb:27:in `kredis_integer`: unknown keyword: :default (ArgumentError)

Implementation

Added the default: keyword argument to all of the following kredis attribute methods:

• kredis_string
• kredis_integer
• kredis_decimal
• kredis_datetime
• kredis_flag
• kredis_float
• kredis_json
• kredis_list
• kredis_unique_list
• kredis_set
• kredis_counter
• kredis_hash
• kredis_boolean

Tests

I did not add new tests for this change as there don't appear to be existing tests for any of the other optional arguments here and this argument would not meaningfully change the DSL output (just allows it to not error when the default: argument is provided). Willing to add tests for this if needed -- leaning on the side of following the existing pattern here.
