Fix: help files use one style

[dustdfg]

I also plan:

1. Use tabs everywhere inside:

   ```json
   ```

2. Use tabs or spaces before default value: in runtime/help/options.md. Currently there are both types of indents but I think spaces will suit better because tab can have different size

3. Yeah it is not about help files but about syntax files so I can then rename the PR to "Fix: runtime use one style". So should yaml files use tabs? I vote for tabs

For 16-color, 256-color and true-color the backquotes might be a bit misleading, since these are not "proper names" (option names, terminal names etc)

Why?

I agree, spaces will suit better.

Currently they use spaces. Why change that?

Furthermore, apparently YAML doesn't allow indentation with tabs.

This is what happens if I change a space to tab in a syntax file:

$ make
GOOS=linux GOARCH=amd64 go generate ./runtime
panic: yaml: line 7: found character that cannot start any token

goroutine 1 [running]:
main.convert({0xc0000b8f0a, 0x1})

exit status 2

Yeah it is solved by another PR...

And there is one file place where json blocks use tabs but in other places it is spaces

One more question. (Only) somewhere in runtime/help/keybindings.md I saw Ctrl-letter use back quotes: Ctrl-e but in other places it is just plain text: Ctrl-e

Might be worth fixing too. Or maybe it's not really important at all.

At least it grabs attention when opened in the editor but in the online github version it doesn't have much sense
