gleam publish: Show hint about republishing instead of hexpm library error

[inoas]

gleam publish on the same version should show an hint on how to republish.

Also because hexpm talks about republishing maybe --republish is better than --replace, but that's minor.

Outdated text

~~For a brief time hex.pm allows republishing on the same version tag it seems, but not gleam publish~~

error: Hex API failure

There was a problem when using the Hex API.

This was error from the Hex client library:

must explicitly express your intention to replace the release

~~I'd like to see a --force or --republish or --overwrite tag. I'd prefer --republish. If given the explicit intention as mentioned in the error would be passed through.~~

Thanks!
