Simon Willnauer 79093e1663 Ensure shrunk indices carry over version information from its source (#22469)
Today when an index is shrunk the version information is not carried over
from the source to the target index. This can cause major issues like mapping
incompatibilities for instance if an index from a previous major version is shrunk.

This commit ensures that all version information from the soruce index is preserved
when a shrunk index is created.

Closes #22373
