Describe the Bug

When I run my jest test on astro 2.1.4

  ● Test suite failed to run

    node_modules/astro/tsconfigs/base.json:28:5 - error TS5023: Unknown compiler option 'ignoreDeprecations'.

    28     "ignoreDeprecations": "5.0"
           ~~~~~~~~~~~~~~~~~~~~

will found this error

in the package node_modules/astro/tsconfigs/base.json have this line

    // TypeScript 5.0 changed how `isolatedModules` and `importsNotUsedAsValues` works, deprecating the later
    // Until the majority of users are on TypeScript 5.0, we'll have to supress those deprecation errors
    "ignoreDeprecations": "5.0"

I think I suppose to use typescript v5 in order to make it works. I know it's build in by astro. So, I check my typescript version and it's 4.9.4.

npm list typescript

Not sure astro should update typescript to be 5? or I need to do something with my jest setup. Beside jest test, the application can build and run normally. Sorry if it's not a bug.

Hello, please update to TypeScript 4.9.5, which added ignoreDeprecations. astro itself just depends on any versions of TypeScript, so reinstalling should be fine. Not sure about ts-jest though, but I'd assume it'd allow you to use 4.9.5

For anyone coming here later like me, if you see this error in VS code, also change the typescript version used to the workspace version. The one that comes with VS code is older than 4.9.5.
