Describe the bug / provide steps to reproduce it

Using Zed's built-in terminal with Delta configured as the pager for something like Git, it's unable to detect light mode. This is in contrast to running the same command (e.g. git show) in Kitty.

Delta can be forced into light mode by configuring it with --light, which exposes how it should look when Zed is in light mode.

Here's Delta's change: dandavison/delta#1615
And here's Lazygit for example fixing compatibility: jesseduffield/lazygit#3419

Environment

Zed stable 0.161.2, macOS 15.1

Can you provide explicit steps to reproduce?
What is the behavior you were expecting / what actually happened?

Here's what I did:

brew install delta
echo -e "FOO=BAR\nBAR=BAZ\n\MOP=POP\n" > a.env
echo -e "FOO=BAR\nBAR=BOP\n\MOP=POP\n" > b.env
delta a.env b.env

One Light

One Dark

And this looks, um fine?

It works now 🤷 Thanks for taking a look.
