Getting Started with Swiftly on Linux gpg import issue

[igorkovalchuk]

https://www.swift.org/keys/all-keys.asc gpg import doesn't work as expected

Steps to reproduce the behavior:

1. Go to https://www.swift.org/install/linux/swiftly/
2. curl https://www.swift.org/keys/all-keys.asc | gpg --import -
3. Error

Expected behavior

gpg imports keys from all-keys.asc file

Actual behavior

gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

Environment details

• OS: Debian 12

Additional context

curl downloads the gzipped all-keys.asc file, but gpg doesn't expect this;
it is possible to see this using the hexdump Linux utility.

Renaming the file to .gz and using gunzip all-keys.asc.gz fixes this.
Today the gzipped asc file length is 12782 bytes, decompressed is 21975 bytes.

Seems that using curl --compressed ... also helps.
