Fail snapshot operations early on repository corruption (#30140)
A NullPointerException is thrown when trying to create or delete
a snapshot in a repository that has been written to by an older 
Elasticsearch after writing to it with a newer Elasticsearch version.

This is because the way snapshots are formatted in the repository 
snapshots index file changed in #24477.

This commit changes the parsing of the repository index file so that 
it now detects a corrupted index file and fails early the snapshot 
operation.

closes #29052
