fix(crater): install awscli from snap

[MarcoIeni]

Ansible in master fails on crater (which is now on ubuntu 24).
This is because awscli is not installed anymore in apt.
With this PR we install aws from snap instead of apt.

How to deploy this:

• uninstall awscli with ssh
• run ansible apply

A newer version of the aws cli will be pulled so maybe there are some breaking changes that we need to fix after. (this should work)

Finally I found the queue empty this morning.

I ran

sudo apt-get remove awscli

but ubuntu couldn't locate the awscli package.

So I manually deleted the aws binary with sudo rm /usr/local/bin/aws

Now I'm running ansible apply.

Ansible finished:

crater.infra.rust-lang.org : ok=128 changed=5 unreachable=0 failed=0 skipped=90 rescued=0 ignored=1

So I'm merging this

Crater still works 🥳
