Unable to build after upgrade from version `7.1.0` to `7.2.4` with `@svgr/webpack`

Bug report

I'm seeing a weird issue after I upgrade postcss-loader from version 7.1.0 to 7.2.4.
My build starts to fail due to the following:

Module build failed (from ./node_modules/@svgr/webpack/dist/index.js):
TypeError: Cannot read properties of undefined (reading 'getSourceFile')
   at getValidSourceFile (/node_modules/typescript/lib/typescript.js:169214:38)

    at Function.Module._load (node:internal/modules/cjs/loader:868:12)
    at Module.require (node:internal/modules/cjs/loader:1057:[19])

I also tested with other 7.2.+ builds, all have the same issue.

Actual Behavior

See above

Expected Behavior

Should be able to build.

How Do We Reproduce?

I spot this when doing dependencies upgrade for a project.
I have @svgr/webpack (version 7.0.0) configured as SVG loader in webpack.config.js

     {
        test: /\.svg$/,
        use: ['@svgr/webpack'],
      },

The build was working properly witih postcss-loader 7.1.0.

Please create reproducible test repo, sorry it is impossible to say what is wrong without it

[annidai]

I'll reopen it if I can create a reproducible test repo for this.
