CLOUDP-394228: Fix public e2e env_variables for managed LB search snippets (#962)

## Summary

- The `env_variables_e2e_public.sh` files for managed LB search snippet
directories (07, 09, 10, 11) were missing the Ops Manager credential
mappings (`OM_*` → `OPS_MANAGER_*`), causing the `om-project` configmap
to be created with placeholder values like `<SET API URL>` instead of
actual Cloud QA credentials
- This caused all 4 `public_kind_code_snippets` tasks to fail with
`unsupported protocol scheme ""` when the operator tried to connect to
Ops Manager
- For external variants (07, 10), extracted shared e2e variables
(external cluster topology, connection strings, Ops Manager overrides)
into `env_variables_e2e_common.sh` sourced by both public and private
env files

## Test plan

- [x] Evergreen patch:
https://evergreen.mongodb.com/version/69ce79039a74900007939618
  - `test_kind_search_external_sharded_managed_lb_snippets.sh`
  - `test_kind_search_sharded_managed_lb_snippets.sh`
  - `test_kind_search_external_rs_managed_lb_snippets.sh`
  - `test_kind_search_rs_managed_lb_snippets.sh`
