<ip>:8086/query?q=show databases this returns only databases that start with a capital letter

**Steps to reproduce:**
List the minimal actions needed to reproduce the behavior.

1. go to dashboard - :8086
2. create a bucket named `t` and another one named `M`.
3. use Postman, add the authorization token and call `:8086/query?q=show databases`

**Expected behavior:**
get both buckets in the json

**Actual behavior:**
I get only buckets that start with a capital letter.

**Visual Proof:**
I can't take a screenshot of the postman right now but I can do it if it's important for some reason.

## About your environment

**Environment info:**
Host machine: `Linux 5.15.0-60-generic x86_64`
`InfluxDB v2.4.0 (git: de247bab08) build_date: 2022-08-18T19:41:15Z`
running in a docker container using the image `influxdb:2.4`.

The query works fine on another machine, using the same container, where the host is `Linux 5.14.0-1058-oem x86_64`

Start by reproducing the `:8086/query?q=show databases` request from Postman against an InfluxDB 2.4 Docker container with buckets named `t` and `M`. Compare the JSON response on the two Linux hosts and determine whether the missing lowercase bucket is caused by the API or the UI; done means both buckets are returned consistently.
