fix(plugin-vite): avoid TS5055

[erickzhao]

When publishing the Vite plugin with @electron/forgers, we ran into a weird issue with yarn build whenever the /dist/ file already existed:

yarn run v1.22.22
$ tsc -b packages
error TS5055: Cannot write file '/Users/erick.zhao/Developer/electron/forge/packages/plugin/vite/dist/Config.d.ts' because it would overwrite input file.

error TS5055: Cannot write file '/Users/erick.zhao/Developer/electron/forge/packages/plugin/vite/dist/VitePlugin.d.ts' because it would overwrite input file.

I took a quick peek at the problem and it seems like removing the reference to typeof import('@electron-forge/plugin-vite') helped fix the problem in build.

LGTM.
