Linux distribution signatures

[vahtras]

I was looking at open issues (e.g. #4186) when I come across some problems with the documentation on the Linux distrubution at https://bitcoin.org/en/full-node#linux-instructions

• The PGP key at https://bitcoin.org/laanwj-releases.asc which is supposed to sign the latest release (according to instructions) has expired

$ gpg laanwj-releases.asc
pub   rsa4096 2015-06-24 [SC] [expired: 2022-02-10]
      01EA5486DE18A882D4C2684590C8019E36C2E964
uid           Wladimir J. van der Laan (Bitcoin Core binary release signing key) <laanwj@gmail.com>

• Further, this key does not appear in the detatched signature file at https://bitcoin.org/bin/bitcoin-core-27.0/SHA256SUMS.asc (linked under "Verify released signature" on the download page)

i$ gpg --verify SHA256SUMS.asc bitcoin-27.0-x86_64-linux-gnu.tar.gz

I hope these are minor documentation errors or that I have made some mistake.

This is my first issue in this project so I apologize if I have violated any guidelines.
