fix(build): update esbuild to 0.25.3

[chezsmithy]

Description

I've noticed a build problem where the 2 year old version of esbuild is no longer pulling binaries which are required to build locally.

I'm noting a question that needs to be resolved:

https://github.com/chezsmithy/continue/blob/e96639f17107def6050f265508949d6a071a0222/extensions/vscode/scripts/prepackage.js#L386

Notes that it pulls a pre-build version of esbuild. Would this also need to be updated to use the latest version as well? I'm assuming so?
