docs: custom instructions support the same languages as style rules

- Remove the 8-language restriction from custom_instructions in the OpenAPI spec
- Rename the language table badge to "Style Rules & Custom Instructions"
- Replace the stale 8-language limit on the style rules guide with a link
  to the supported languages page
- Remove the style rules language info box from the supported languages
  page (the table already shows this) and its generator script

-- Style rule lists support target languages `de`, `en`, `es`, `fr`, `it`, `ja`, `ko`, and `zh`
+- Style rule lists support the target languages listed in [Languages supported](/docs/getting-started/supported-languages)
 - There is no limit on the number of configured rules per list
 - A list can hold up to 200 custom instructions (this cap may be adjusted per plan tier in the future); each instruction prompt is limited to 300 characters
 - If you need more than 200 custom instructions, split your rules across multiple style rule lists for different content types
