Samples of changelog.xml in documenation have wrong path to xsd files

See original GitHub issue

Environment

Liquibase Version: 4.9.1

Liquibase Integration & Version: spring boot

Liquibase Extension(s) & Version: none

Database Vendor & Version: Oracle 19

Operating System Type & Version: Linux Mint 20.3

Description

I believe these snippets of changelog.xml in documentation are wrong: https://docs.liquibase.com/concepts/changelogs/working-with-changelogs.html https://docs.liquibase.com/tools-integrations/springboot/springboot.html

String http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-4.9.0.xsd should actually be: http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-4.9.xsd (without trailing .0)

Such files (without .0) can be found in liquibase-core.jar and can be accessed via http.

Steps To Reproduce

Make empty springboot application with empty changelog.xml taken from documentation and try to run it.

Actual Behavior

Exception during application startup:
