Tiny documentation update

[5uperpalo]

Hi,

could you please make a tiny documentation update for influxdb2 helm chart?
I just spend a day on trying to figure out why I am not able login to UI until I realized that I did not correctly understand the Note in helm chart:

Note: with enabled persistence, admin password is only set once during the initial deployment. The password is not changed when InfluxDB 2 is re-deployed with different password.

I thought that under re-deployment you mean uninstall/install, and not that I have to also delete related pvc as it is not automatically deleted during helm uninstall, i.e.:

mulinka@saiacheron:~$ helm uninstall influx -n influx
These resources were kept due to the resource policy:
[PersistentVolumeClaim] influx-influxdb2

release "influx" uninstalled

so I was "re-deploying", i.e. uninstalling/installing/upgrading but none of it made any difference as the initial pvc with initial random password was always being used.

Could you please either (i) fix the user/pass update when the deployment is updated? or (ii) change the helm chart note to something like:

Note: with enabled persistence, admin password is only set once during the initial deployment. The password is not changed when InfluxDB 2 is re-deployed with different password. You **HAVE TO** delete the pvc in order to change the admin password!
