Update osbuild/images to v0.40.0

In addition, simplify the SPEC file to not have to update the minimum
required osbuild version gazillion times, but just once.

Update the minimum required osbuild version to v109, due to changes in
grub2 stages required by the new osbuild/images version.

Update osbild SHA in Schutzfile to v109.

 ## [Unreleased]
 
+## [1.23.0] 2024-02-06
+
+This release contains the first stable, `v1`, release of the following modules:
+
+- `go.opentelemetry.io/otel/bridge/opencensus`
+- `go.opentelemetry.io/otel/bridge/opencensus/test`
+- `go.opentelemetry.io/otel/example/opencensus`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`
+- `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`
+
+See our [versioning policy](VERSIONING.md) for more information about these stability guarantees.
+
+### Added
+
+- Add `WithEndpointURL` option to the `exporters/otlp/otlpmetric/otlpmetricgrpc`, `exporters/otlp/otlpmetric/otlpmetrichttp`, `exporters/otlp/otlptrace/otlptracegrpc` and `exporters/otlp/otlptrace/otlptracehttp` packages. (#4808)
+- Experimental exemplar exporting is added to the metric SDK.
+  See [metric documentation](./sdk/metric/EXPERIMENTAL.md#exemplars) for more information about this feature and how to enable it. (#4871)
+- `ErrSchemaURLConflict` is added to `go.opentelemetry.io/otel/sdk/resource`.
+  This error is returned when a merge of two `Resource`s with different (non-empty) schema URL is attempted. (#4876)
+
+### Changed
+
+- The `Merge` and `New` functions in `go.opentelemetry.io/otel/sdk/resource` now returns a partial result if there is a schema URL merge conflict.
+  Instead of returning `nil` when two `Resource`s with different (non-empty) schema URLs are merged the merged `Resource`, along with the new `ErrSchemaURLConflict` error, is returned.
+  It is up to the user to decide if they want to use the returned `Resource` or not.
+  It may have desired attributes overwritten or include stale semantic conventions. (#4876)
+
+### Fixed
+
+- Fix `ContainerID` resource detection on systemd when cgroup path has a colon. (#4449)
+- Fix `go.opentelemetry.io/otel/sdk/metric` to cache instruments to avoid leaking memory when the same instrument is created multiple times. (#4820)
+- Fix missing `Mix` and `Max` values for `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric` by introducing `MarshalText` and `MarshalJSON` for the `Extrema` type in `go.opentelemetry.io/sdk/metric/metricdata`. (#4827)
+
+## [1.23.0-rc.1] 2024-01-18
+
+This is a release candidate for the v1.23.0 release.
+That release is expected to include the `v1` release of the following modules:
+
+- `go.opentelemetry.io/otel/bridge/opencensus`
+- `go.opentelemetry.io/otel/bridge/opencensus/test`
+- `go.opentelemetry.io/otel/example/opencensus`
+- `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`
