Update theme preview scripts and screenshots (#909)

Browse source

Lots of changes - Pretty every change needed to be made before updating
the preview screenshots, so they all end up in the same PR here:

* `preview-generate-screenshots.nu` now generates the previews and
screenshots all in one pass rather than requiring a separate file.

* Adds a new method for generating screenshots using PowerShell with no
third-party application required. Created new function for choosing the
method that is used to generate screenshots.

* Fixes background color on `nushell-dark` and `nushell-light` themes.

* Fixes bug where `cursor` setting (and perhaps one other) was getting
dropped from the preview table (`math ceil` was needed rather than `math
floor`)

* Fixes `cellpath` setting - Was changed to `cell-path` a while back but
never updated in the themes. All themes and their previews were
regenerated. Custom themes were manually adjusted.

* **Important:** I did not update `make.nu` to fix this (yet) since
@amtoine has a open PR against it that has not been merged yet. Easier
to either put that change in that PR or do it after that one has been
merged.

* Adds `mod.nu` in the root of the `themes` module. Moves some of the
previous script commands such as `preview_terminal`,
`preview_theme_small`, etc. over to the module. Makes for cleaner usage.

* Note: The completion functions in the scripts have been broken for
several months. I did not fix this at this point.

* `preview_theme_small` (and others) renamed to use spaces in command
name, so it is now `preview theme small`.

* Fixes bug of my own making that prevented several custom themes from
working.

* Refactors the "list to columns" code to use `group` (will need to be
updated to `chunks` in 0.96)
* Suppresses the indices column in the preview table
* Removes the column headers entirely since they don't serve any purpose
in this type of "columnar table"
