Describe the Bug

The preact template logs warnings when installing.

 WARN  Issues with peer dependencies found
.
└─┬ @astrojs/preact 4.0.1
  └─┬ @preact/preset-vite 2.8.2
    └── ✕ unmet peer vite@"2.x || 3.x || 4.x || 5.x": found 6.0.5 in @astrojs/preact

@preact/preset-vite has been pinned since this PR:

• fix(deps): update all non-major dependencies #11318

What's the expected result?

The template can be installed without any warnings.

If somebody would like to check if it's ok to unpin and upgrade @preact/preset-vite that would be great.

fwiw downgrading Astro (in order to downgrade vite) does not fix this issue and produces the following setup (pnpm why vite):

dependencies:
@astrojs/preact 4.0.1
├─┬ @preact/preset-vite 2.8.2
│ ├─┬ @prefresh/vite 2.4.6
│ │ └── vite 6.0.7 peer
│ └── vite 6.0.7 peer
└── vite 6.0.7
astro 4.16.18
├── vite 5.4.11
└─┬ vitefu 1.0.5
  └── vite 5.4.11 peer

Note that vite 6.0.7 is listed as a direct dependency of @astrojs/preact here, while Astro itself uses a different version. It seems that there is a version conflict within the @astrojs/preact package.

Edit: the latest known good setup is [email protected] @astrojs/[email protected]. I have not tested whether it's safe to ignore the warning as I am currently resolving other unrelated conflicts that may or may not impact testing. Having @preact/preset-vite upgraded would be the optimal solution if possible.
