This Pr fix the issue about deprecated warning reference from #117

Any ETA for its release?

@riderx can we also update the build cli esbuild target from es2021 to node20?

From

pages-action/package.json

Line 7 in aeb0d93

"build": "npx esbuild src/index.ts --bundle --platform=node --target=es2021 --outfile=index.js",

To

"build": "npx esbuild src/index.ts --bundle --platform=node --target=node20 --outfile=index.js",

This is not that big of a deal and it should have been already merged to comply with the deprecation 😢

And you can update the description to

Closes #117.

That issue will be closed once this PR gets merged.

Any reason this hasn't been merged yet?

[Fabio1988]

what's the blocker of this?

[riderx]

Thanks @andykenward i modified it!
I'm not a core contributor, so I cannot do much more than a PR

[riderx]

Maybe @WalshyDev if you can report internally it, it would be super nice <3

Also need to update @types/node to 20. Plus we can remove the usage of the NPM package "undici" for fetch as Node.js 20 supports fetch natively.
