@swc/core's binary does not handle folders with .js suffix well

[pan93412]

Describe the bug

I found that SWC mistakenly treats a folder with the .js suffix as a file, which introduces this bug:

$ ./swc-darwin-arm64-1.7.26 compile .
Error: Failed to open file ./vendor/chart.js

Caused by:
    Is a directory (os error 21)

Note that the binary is downloaded from the GitHub Releases:

wget https://github.com/swc-project/swc/releases/download/v1.7.26/swc-darwin-arm64 -O swc-darwin-arm64-1.7.26 && chmod +x swc-darwin-arm64-1.7.26

Expected behavior

It should be able to build. For example, when I rename chart.js to charts:

$ mv vendor/chart.js/ vendor/chartjs

$ ./swc-darwin-arm64-1.7.26 compile .
./vendor/chartjs/chart.js.min.js
console.log("hi chart.js");

./index.ts
console.log("Hello");

Actual behavior

$ mv vendor/chartjs vendor/chart.js

$ ./swc-darwin-arm64-1.7.26 compile .
Error: Failed to open file ./vendor/chart.js

Caused by:
    Is a directory (os error 21)
