docs: make changelog up to date

this is a pretty big commit which mainly contains a refactor
and breaking change to how command completions are done.

before that, a hilbish.completion interface has been added
which for now just has 2 functions (`files` and `bins`)
for completions of normal files and executables.

hilbish.complete is now expected to return a table of
"completions groups," which are as the name suggests a group
for a completion. a completion group is a table which has
the fields `type`, which can be either `list` or `grid`,
and `items`, being an array (or string keyed table) of items

if an item is string keyed the item itself is the key name
and the value is a table with the first value in it being the
description for the item. this description is only applied
with the list type.

this is probably the longest commit message ive written

+- `hilbish.complete()` has had a slight refactor to fit with the new readline library.
+It now expects a table of "completion groups" which are just tables with the
+`type` and `items` keys. Here is a (more or less) complete example of how it works now:
+  ```lua
+    hilbish.complete('command.git', function()
+      return {
+        {
+          items = {
+            'add',

+          type = 'list'

+      }
+    end)
+  ```
