v2.0.0-beta - arm32 download links to arm64 binary, please create an arm32 binary

When attempting to download an arm32 build of InfluxDB v2 beta, the 'ARM' link (arm32) links to an arm64 download.


__Steps to reproduce:__
On an arm32 device (Raspberry Pi Zero)

```
wget https://dl.influxdata.com/influxdb/releases/influxdb_2.0.0-beta.10_linux_arm64.tar.gz
tar xvfz influxdb_2.0.0-beta.10_linux_arm64.tar.gz
cd influxdb_2.0.0-beta.10_linux_arm64
./influx --version
```

You will get this error:

> -bash: ./influx: cannot execute binary file: Exec format error

~/influxdb_2.0.0-beta.10_linux_arm64 $ ./influx --version
-bash: ./influx: cannot execute binary file: Exec format error

__Expected behavior:__
Downloaded binary for arm should work on arm32 device (Raspberry Pi Zero)

__Actual behavior:__
Downloaded binary was for arm64, so the arm32 device could not execute it.

__Environment info:__

* System info: Linux 4.19.97+ armv6l
* InfluxDB version: (I can't run this)
