kata-deploy: Install jq from GitHub

`jq` coming from alpine is in its 1.6 version, and that has a bug that
hits us quite hard, as it changes a float to an int whenever the number
is in the `x.0` format.

One example is:
```bash
/ # jq --version
jq-1.6
/ # echo '{"foo": 1.0}' | jq .foo
1
```

With this in mind, let's switch, at least for now, to using the `jq`
released directly on github, as it does address the issue we've been
hitting.
```bash
⋊> Downloads ./jq-linux-amd64 --version
jq-1.7
⋊> Downloads echo '{"foo": 1.0}' | jq .foo
1.0
```

Fixes: #8678
