build: fix ARGO_LOG_LEVEL -> ARGO_LOGLEVEL

[agilgur5]

Fixes kitproj/kit#41 and fixes the issue in this comment: #11879 (comment)

Motivation

• credit to Julie and Alex for debugging this, I merely confirmed the issue and fixed it

• the flag is loglevel and with the automatic env prefix, that becomes ARGO_LOGLEVEL as an env var

  • ARGO_LOG_LEVEL was a misconfiguration / typo as such

Modifications

• Find+Replace all instances of ARGO_LOG_LEVEL -> ARGO_LOGLEVEL

  • they were only in the Makefile and the tasks.yaml

• also add watch list for the ui-deps task after my dive into task (this line from build: replace kit with task #11928)

  • it seemed like kit kept re-installing deps when this was missing
    • actually, kit might be missing this feature? 🤔 not sure as the docs are unclear here: Disable watch option kitproj/kit#40 (comment) / "Memoization" / work avoidance / don't run task if sources haven't changed kitproj/kit#46. this change may end up just having it auto-restart when deps change, which is still a good change
      • NOTE that ui/node_modules was removed here, as that caused an infinite restart loop when there was a dep change

Verification

After setting the env variable in tasks.yaml, the Controller is now showing debug logs during a kit run:

controller: time="2023-10-10T20:51:00.001Z" level=info msg="omniscient-python is suspended, skipping execution" namespace=argo workflow=omniscient-python
controller: time="2023-10-10T20:51:00.015Z" level=debug msg="Patch cronworkflows 200"
port-forward: Handling connection for 9000
port-forward: Handling connection for 9000
controller: time="2023-10-10T20:51:04.973Z" level=debug msg="Get leases 200"
controller: time="2023-10-10T20:51:04.986Z" level=debug msg="Update leases 200"

Notably, I realized that the Server doesn't even take a loglevel. Its parent command, argo, does take a loglevel, and so that should be inherited, but it seems like that flag doesn't pass through to Viper to be read as an env variable automatically.
That will require further fixes -- a CLI flag, like --loglevel=debug, is currently required for the Server as the env var is currently ignored.

• EDIT: Fixed this in fix(server): allow passing loglevels as env vars to Server #12145
