Bump Databricks Go SDK to 0.120.0 (#4698)

## Why

Keeps the CLI up to date with the latest Go SDK release (v0.120.0).

## Changes

Bumps `github.com/databricks/databricks-sdk-go` from v0.119.0 to
v0.120.0. Both versions share the same OpenAPI SHA, so no generated code
changes are needed.

## Test plan

- [x] `make generate` produced no code diffs
- [x] `make lintfull` passed (0 issues)
- [x] Unit tests (`build`, `schema`, `dresources`, `resources`) passed
- [x] Acceptance tests (`refschema`, `account-help`, `workspace-help`)
passed
- [x] `make checks` passed
