Rename module SolidusTaxJar to SolidusTaxjar

In order for the Zeitwerk loader to properly identity our classes
from the file names, we should remove camel casing from this name
that isn't consistent with underscores in the file name itself.

-This is not a fork of [spree_taxjar](https://github.com/vinsol-spree-contrib/spree_taxjar), like [solidus_taxjar](https://github.com/boomerdigital/solidus_taxjar). Instead of using a custom calculator, `SuperGood::SolidusTaxJar` uses the new configurable tax system [by @adammathys](https://github.com/solidusio/solidus/pull/1892) introduced in Solidus v2.4. This maps better to how the TaxJar API itself works.
