Replace wezterm with ghostty

wezterm was consuming quite a lot of memory, and I wasn't really using
any of the advanced features.

I will reconsider if ghostty ends up using just as much.

+#
+#   /home/j/.config/ghostty/config
+#
+# The template does not set any default options, since Ghostty ships
+# with sensible defaults for all options. Users should only need to set
+# options that they want to change from the default.
+#
+# Run `ghostty +show-config --default --docs` to view a list of
+# all available config options and their default values.
+#
+# Additionally, each config option is also explained in detail
+# on Ghostty's website, at https://ghostty.org/docs/config.
+#
+# Ghostty can reload the configuration while running by using the menu
+# options or the bound key (default: Command + Shift + comma on macOS and
+# Control + Shift + comma on other platforms). Not all config options can be
+# reloaded while running; some only apply to new windows and others may require
+# a full restart to take effect.

+# # separated by equals signs.

+# key = value
+#
+# # Any line beginning with a # is a comment. It's not possible to put
+# # a comment after a config option, since it would be interpreted as a
+# # part of the value. For example, this will have a value of "#123abc":
+# background = black
+#123abc
+# theme = Dark Modern
+# theme = Soft Server
+# theme = Zenwritten Dark
