Update archives for migrations multiple nodes test (#209667)

fix https://github.com/elastic/kibana/issues/167676 for 9.0 promotion

steps taken:
1. Start Node01: 
`yarn es snapshot --version=8.19.0 --data-archive
src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_01.zip
--base-path .es/node01`

2. Start Node02: 
`yarn es snapshot --version=8.19.0 --data-archive
src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_02.zip
--base-path .es/node02`

3. Wait for both nodes to start and be ready

4. Stop both ES nodes

5. change into the directory for node01:
`cd .es/node01/8.19.0`

6. Remove (or move) the outdated archive:
`rm
../../../src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_01.zip`

7. zip the updated data and store as the original test filename in the
test directory:
`zip -r
../../../src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_01.zip
data -x "*/\.*"`

Repeat these steps for node02:

8. `cd ../../../`
9. `cd .es/node02/8.19.0`
10. `rm
../../../src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_02.zip`
11. `zip -r
../../../src/core/server/integration_tests/saved_objects/migrations/archives/7.13.0_5k_so_node_02.zip
data -x "*/\.*"`

12. `cd ../../../`
13. `git commit -m "Updated archives" && git push`

### Identify risks

Data archives have to be updated for every major.last before a new major
is released.
Should updating the archives not resolve test failures, there may be a
bug elsewhere in the stack. If so, carefully inspect the error logs to
determine the cause.
