Bump timeout when waiting for crates.io publish (#4213)

## Motivation and Context
<!--- Why is this change required? What problem does it solve? -->
<!--- If it fixes an open issue, please link to the issue here -->
We have occasionally seen errors when crates.io takes longer than 10
seconds to show our crates as published. This change relaxes that
timeout to 60 seconds.
