fix link to download latest icrc1-ledger

[marc0olo]

I recognized we introduced a link which doesn't work in this PR that got merged recently: #1073

i think its better to point to a specific commit in case the file get's renamend or put into a different directory

I think this is in general not very convenient at this point, but I see your point. IMO it is fine for the moment and we should rather consider to create a dedicated repository just for scripts to be (re-)used across different repos.

personally I prefer relying on master over some potentially very outdated commit. if the script needs to change for whatever reason, we ultimately have a similar issue.

@letmejustputthishere I switched to a specific commit now. my concerns above remain though 😛

the issue is also present here

https://github.com/dfinity/examples/tree/master/rust/icp_transfer
https://github.com/dfinity/examples/tree/master/rust/token_transfer
https://github.com/dfinity/examples/tree/master/rust/token_transfer_from

do you mind fixing them as well?

@letmejustputthishere I think I only missed https://github.com/dfinity/examples/tree/master/rust/icp_transfer which I fixed now, too
