User facing changelog

Fixes a TypeScript error when specifying the configFile option for @cypress/vite-dev-server.

Additional details

When using the configFile option in @cypress/vite-dev-server I recieved a TS error. This is because the TS types for the startDevServer method use UserConfig from Vite, but that type does not include the configFile property, however InlineConfig does because it extends from UserConfig.

I replaced references of UserConfig with InlineConfig.

FYI, the TS error message was:

Type '{ configFile: string; }' is not assignable to type 'UserConfig'.\n  Object literal may only specify known properties, and 'configFile' does not exist in type 'UserConfig'.

How has the user experience changed?

There is no change to the user experience.

Can any maintainers help me to fix the build issues. Each time I update my branch to be up-to-date with the base different tests fail.. I only changed a TypeScript type and it won't have affected any of the failing tests..

@mrmartineau I believe we merged something a bit quickly and there is a need to update yarn.lock for the vue tests to pass.
I updated your branch with the last commit, it should make it work.

Good catch thank you

Hm, I wonder why npm/vue is now failing. It's passing fine on my local machine.

[lmiller1990]

Ok, it passes now.
