Update to nushell 0.85.0 (#155)

* tm syntax: remove verification behind command
It surely has been useful in early stage of the syntax
but it's seems to have no impact now

* tm syntax: add variable fields in "variables"
get rid of non-fixed text width lookbehind, incompatible with PCRE regex

* update changelog for 1.6.0

* updates for nushell 0.85.0 release

 ## Regex Engine
 
 TIL - VSCode uses regexes for language syntax highlighting in \*.tmLanguage.json files. Those regexes and json are based on Textmate, which uses (and here is the secret-sauce) `oniguruma` flavor of syntax. See the cheat-sheet for the [syntax here](https://github.com/kkos/oniguruma/blob/master/doc/RE). Also there's a rust-crate called `onig` or `rust-onig` if we wanted to write something to help create compatible regular expressions.
+
+## list-to-tree
+
+glcraft wrote a fancy program to create regexes for the extension. Here's the steps to use it.
+
+1. clone and cargo install the tool. https://github.com/glcraft/list-to-tree
+2. on windows create a set of commands. `scope commands | where is_builtin == true and is_custom == false | get name | to text | save win-cmds_20230919.txt`
+3. on linux create a set of commands. `scope commands | where is_builtin == true and is_custom == false | get name | to text | save lin-cmds_20230919.txt`
+4. combine these two files, sort, and uniq them. `open win-cmds_20230919.txt | lines | append (open lin-cmds_20230919.txt | lines) | sort | uniq | save cmds_20230919.txt`
+5. run list-to-tree `list-to-tree --input cmds_20230919.txt --format regex`
+6. copy-n-paste the results to the `nushell.tmLanguage.json` file in the appropriate place (search for "list-to-tree"). Be careful, this can be tricky.
+7. test out the changes with F5 and viewing some scripts.
