I've moved the bank website credentials to a shared collection in
Bitwarden and made them accessible to an account dedicated to
`xactfetch`. Using the `pinentry-stub` script, `rbw` can now
auto-unlock the vault, using the password in the file referred to by the
`PINENTRY_PASSWORD_FILE` environment variable. This means that
`xactfetch` can now run completely automatically, without any input from
me.
