workaround for:
Bitwarden .deb can't export vault, as tracked in: bitwarden/clients#19137
as suggested in root cause analysis by @g0r3 in: bitwarden/clients#20915
cat the install.sh and use it as a guide. Don't run it blindly.
Only tested on Debian 13 amd64.
This bypasses an attempt at memory hardening and the code isn't audited, so do something else if it's important.
Odds are this is a one-and-done since it works on my PC so please fork and fix if needed.
