regression: broken support for custom themes

[vladmandic]

typedoc version: typedoc 0.22.3
other versions: typescript 4.4.3 with node 16.5.0 on ubuntu 21.04 inside wsl2 on windows 11

typedoc --theme custom test.js

throws error:

Error: The theme 'custom' is not defined. The available themes are: default
Error: Documentation could not be generated due to the errors above.

same when using typedoc via api and setting td.options.theme (which is a type: string, so not much else to do there)

this used to work before latest update

HTML output is now rendered with JSX instead of Handlebars, closes #1631.
This change provides major performance benefits, reducing rendering time by up to 10x for several benchmarked projects.
It also allows themes to be easily type checked, preventing mistakes when creating custom themes.
Removing Handlebars also fixed memory leaks when --watch was specified due to Handlebar's caching mechanism.
This change breaks all existing custom themes, so a theme created for v0.21 or earlier will not work in v0.22.
See internal-docs/custom-themes.md for documentation on how to create a custom theme in v0.22.

that's fair - but cli output should be noting that input param is not pointing to a valid theme

It does, you even included it in your original post!

this is anything but clear

Error: The theme 'custom' is not defined

but ok, closing as by-design
