Injected markdown overrode doc comment color

Languages that inject markdown into documentation strings/comments (e.g. Elixir
@doc/@moduledoc) rendered their prose in the bright foreground color instead of
the muted comment color. Zed's markdown grammar captures every (paragraph) as
@text, and the theme mapped text → c.text, which sat on top of the parent
comment.doc highlight.

Fix: remove the text syntax rule. Zed only pushes a highlight when the capture
resolves to a theme key, so with no text rule the paragraph inherits the
enclosing style. Plain .md files are unaffected: unhighlighted paragraphs fall
back to the editor's default colors.text, which is the same value.

Zed's bundled themes already follow this convention:

• One (assets/themes/one/one.json),
• Ayu (assets/themes/ayu/ayu.json), and
• Gruvbox (assets/themes/gruvbox/gruvbox.json)

each define text.literal but no bare text rule, so injected markdown prose
inherits the enclosing style (e.g. comment.doc) in those themes.

Screenshots

Before

Unusable. Doc comments inject markdown, so everything is just normal bright text. Comments don't look like comments.

After

Comments look like comments, and sanity is restored.
