🛑 Breaking changes 🛑

• all: bump minimal Go version to 1.20 (#​474)

💡 Enhancements 💡

• multimod: ignore excluded-modules when using sync to update dependencies (#​442)
  This allows users of the sync command to sync all modules in a monorepo, including
  those listed in the excluded-modules. This is useful for repositories where some modules
  may not yet be ready for releasing (therefore listed under excluded-modules) but their
  dependencies still need to be managed via multimod.

• crosslink: Add --skip flag to ignore specified go modules (#​480)

• multimod: add support for --commit-hash to allow users to overwrite the tag in a versions.yaml file (#​422)
  This feature allows users to specify a tag (i.e. main) when they want to update
  modules.

• chloggen: support a custom changelog summary template (#​501)
  The changelog summary template can be customized by configuring a custom template with the summary_template configuration setting.
  The default template provides a starting point for a custom template: https://github.com/open-telemetry/opentelemetry-go-build-tools/blob/v0.13.0/chloggen/internal/chlog/summary.tmpl
