[DOCS] Homedir path in SALT.RENDERERS.GPG (ENCRYPTING DATA) are missing in few examples - bash/awk/perl

Description
In order to encrypt data homedir path must be set to /etc/salt/gpgkeys
echo -n 'supersecret' | gpg --trust-model always -ear - gpg: [stdin]: encryption failed: No public key should be the error if there is no gpg keys in user home dir.

Suggested Fix

To add missing homedir path "--homedir /etc/salt/gpgkeys" to all commands below:

echo -n 'supersecret' | gpg --homedir /etc/salt/gpgkeys --trust-model always -ear

awk

ciphertext=echo -n "supersecret" | gpg **--homedir /etc/salt/gpgkeys** --armor --batch --trust-model always --encrypt -r user@domain.com | awk '{printf "%s\\n",$0} END {print ""}'

Perl

ciphertext=echo -n "supersecret" | gpg **--homedir /etc/salt/gpgkeys** --armor --batch --trust-model always --encrypt -r user@domain.com | perl -pe 's/\n/\\n/g'

Open the Salt documentation page at ref/renderers/all/salt.renderers.gpg.html and review the encryption examples for the basic, awk, and Perl commands. Confirm that each command includes --homedir /etc/salt/gpgkeys, then check the rendered page to ensure the examples consistently show the required key-directory path.
