[BUG] `doppler secrets get` waits a few seconds before exiting

[190n]

Describe the bug
When I try to fetch an individual secret with doppler secrets get, the secret is printed quickly but then the process sometimes keeps running for 5-10 seconds before exiting. This makes scripts that rely on doppler secrets get very slow.

To Reproduce
Steps to reproduce the behavior. Please include output from running the command with --debug.

1. Run time doppler secrets get TEST_SECRET_PLS_DELETE -p api-server --config prd --plain --debug (substitute secret, project, and config names that actually exist)

Output:

Debug: Using config dir /Users/ben/.doppler
Debug: Using config file /Users/ben/.doppler/.doppler.yaml
Debug: Reading config file
Debug: Retrieving token from system keyring
Debug: Sending anonymous analytics payload: '{"command":"doppler.secrets.get"}'
Debug: Performing HTTP POST to https://cli.doppler.com/v1/analytics
Debug: Performing HTTP GET to https://api.doppler.com/v3/configs/config/secrets?config=prd&include_dynamic_secrets=false&project=api-server&secrets=TEST_SECRET_PLS_DELETE
Debug: Request ID d735992d-8a53-4e76-b6fc-16180c00d512
test secret
doppler secrets get TEST_SECRET_PLS_DELETE -p api-server --config prd --plain  0.01s user 0.02s system 0% cpu 4.787 total

It prints all the output including the secret value very quickly, but intermittently it takes a very long time to exit (4.7 seconds in the above example)

Expected behavior
Doppler should immediately exit
