BUG: Wrong link in macos install instructions

**Describe the bug**
There's an issue in the install step for Macos.

**To Reproduce**
Steps to reproduce the behavior:
1. Copy and run the following code in your terminal:
```
curl -LO https://github.com/ceramicnetwork/rust-ceramic/releases/download/latest/ceramic-one_aarch64-apple-darwin.tar.gz
tar zxvf ceramic-one_aarch64-apple-darwin.tar.gz
```
Results in the following error:
```
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 9 100 9 0 0 21 0 --:--:-- --:--:-- --:--:-- 21
tar: Error opening archive: Unrecognized archive format
```

It seems like it's because `latest` isn't a valid tag and I'm just downloading the error page into the file. It does work if I replace it with a url with a valid version: `https://github.com/ceramicnetwork/rust-ceramic/releases/download/v0.24.0/ceramic-one_aarch64-apple-darwin.tar.gz`

**Expected behavior**
The readme should have install instructions that work and always install the latest version.
