JIRA: https://xero.atlassian.net/browse/ZAV-192
Epic: https://xero.atlassian.net/browse/ZAV-180

Description

As part of the South Africa VAT rate changes 2025, we need to create some new SystemGSTCodes. These codes are:

SROUTPUT25
CAPOUTPUT25
ACC28PLUS25
ACCUPTO2825
CIUOUTPUT25
SHOUTPUT25
CAPINPUT25
SRINPUT25
CIUINPUT25
BADDEBT25

These codes have been added to the ReportTaxType enum in the open API spec.

These codes have also been added to the TaxType enum but I've noticed there are some pre-existing SystemGSTCodes for ZA VAT that are not included in this enum. So I have added these too:

ACC28PLUS
ACCUPTO28
SHOUTPUT
OTHEROUTPUT
IMINPUT
BADDEBT
OTHERINPUT
ZRINPUT

I've been using this guide for a similar change for Singapore tax rates and this appears to be what was done in this PR.

I believe adding values to these enums creates a breaking change.

BTW - the TaxType enum does not appear to be referenced by any other entity in the spec, so I'm unsure how this gets used.
