Floyd Wang bc17491527 gpui: Revert grid template columns default behavior to align with Tailwind (#44368)
When using the latest version of `GPUI`, I found some grid layout
issues. I discovered #43555 modified the default behavior of grid
template columns. I checked the implementation at
https://tailwindcss.com/docs/grid-template-columns, and it seems our
previous implementation was correct.

If a grid layout is placed inside a flexbox, the layout becomes
unpredictable.

```rust
impl Render for HelloWorld {
    fn render(&mut self, _window: &mut Window, _cx: &mut Context<Self>) -> impl IntoElement {
        div()
            .flex()
            .size(px(500.0))
            .bg(rgb(0x505050))
            .text_xl()
            .text_color(rgb(0xffffff))
            .child(
                div()
                    .size_full()
                    .gap_1()
                    .grid()
                    .grid_cols(2)
                    .border_1()
                    .border_color(gpui::red())
                    .children((0..10).map(|ix| {
                        div()
                            .w_full()
                            .border_1()
                            .border_color(gpui::green())
                            .child(ix.to_string())
                    })),
            )
    }
}
```

I also placed the grid layout example inside a flexbox too.

I tested the changes from the previous PR, and it seems that setting the
table's parent to `v_flex` is sufficient to achieve a non-full table
width without modifying the grid layout. This was already done in the
previous PR.

I reverted the grid changes, the blue border represents the table width.

/>

So, I believe we should revert to this implementation to align with
tailwindcss behavior and avoid potential future problems, especially
since the cause of this issue is difficult to pinpoint.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
