fix(install): do not use curl installed through snap (#5442)
* fix: Do not install with snap-curl

Snap-installed curl doesn't work: when trying to download files from
GitHub, it either fails to download the file, or fails to write the
output at all.

Prevent a curl program which is installed with snap from being used to
download starship.

* Update install.sh

* Minor changes to formatting and wording
