aerc: update to 0.19.0

Important Upstream Updates:
- Drop support for go 1.20 and older
- The location of the command history file has changed to
  `${XDG_STATE_HOME:-$HOME/.local/state}/aerc/history`.
- The `html` filter is now enabled by default, making `w3m` a weak runtime
  dependency. If it is not installed, viewing HTML emails will fail with an
  explicit error.

Other Updates:
- New `:redraw` command to force a repaint of the screen.
- New `head` and `tail` templates functions for strings.
- New `{{.AccountFrom}}` template variable.
- Replying to all will include the Sender in Cc.
- Reply to addresses in `From` and `Reply-To` headers with `:reply -f`.
- Builtin `calendar` filter shows empty attendee list.
- Terminal-based pinentry programs (e.g. `pinentry-curses`) now work properly.
- Notmuch searches which explicitly contain tags from `exclude-tags` now return
  messages.
- Invitations now honor the `:send -a` flag.
- Remove unwanted less than symbol from In-Reply-To header when Message-ID uses
  folding.
- Aliases are now taken into account correctly when replying to own messages
  such as from the Sent folder or via a mailing list.
- Some SMTP servers do not strip `Bcc` headers. aerc now removes them before
  sending emails to avoid leaking private information.
- GPG signatures and encrypted parts now use CRLF line endings as required by
  RFC 5322.
- Template function `quote` only prefixes with a space if at quote depth `1`.
- Path completion now uses the normal filtering mechanism, respecting case
  sensitivity and the fuzzy completion option.
