docs: fix swagger tags for license endpoints (#21101)

## Summary

Change `@Tags` from `Organizations` to `Enterprise` for `POST /licenses`
and `POST /licenses/refresh-entitlements` to match the `GET` and
`DELETE` license endpoints which are already tagged as `Enterprise`.

## Problem

The license API endpoints were inconsistently tagged in the swagger
annotations:
- `GET /licenses` → `Enterprise` ✓
- `DELETE /licenses/{id}` → `Enterprise` ✓
- `POST /licenses` → `Organizations` ✗
- `POST /licenses/refresh-entitlements` → `Organizations` ✗

This caused the POST endpoints to be documented in the [Organizations
API docs](https://coder.com/docs/reference/api/organizations) instead of
the [Enterprise API
docs](https://coder.com/docs/reference/api/enterprise) where the other
license endpoints live.

## Fix

Simply updated the `@Tags` annotation from `Organizations` to
`Enterprise` for both POST endpoints.

This was an oversight from the original swagger docs addition in #5625
(January 2023).
