pin SWC again to fix cli building

[jkelleyrtp]

swc keeps breaking semver in patch releases :(

pin yet another crate of theirs

Closes #2878

[ed-li]

cargo update is ignoring this pin because the swc_ecma_transforms_proposal dependency is for manganis/cli-support

swc (and swc_common) were pinned in DioxusLabs/manganis#60, but the original issue has since been resolved and [email protected] through 0.284.0 are incompatible with [email protected]: swc-project/swc#9455

[email protected] fixes this: swc-project/swc@238ba8b1d2220202129595185bd4411b9415cc99

Fixed upstream in https://github.com/DioxusLabs/manganis/pull/67
