process is not polyfilled if viteConfig.define is used to define, for example, a static environment variable in the form of process.env.var_name

[rdsedmundo]

Problem

• I'm using Sanity Studio V3 and they define a process.env.MODE variable using Vite's define config.
• This causes the process polyfill module to not be applied, and instead process becomes simply { env: { MODE: value } }, due to this OR condition here:

globalThis.process = globalThis.process || __process_polyfill

Solution
We should probably merge the objects somehow, or have a separate option that would allow this.

Maybe dupe of #71 ?

If anyone is facing this, In our app we are in the process of migrating from create-react-app to Vite and I created this package patch (it's for v0.21.0 only) as an interim solution.
