fix(chore): Minor refactor

[jamesgeorge007]

Use process.platform instead of os.platform() to maintain consistency.

@joaomoreno Makes sense 🤔

[raix]

process.platform was added in v0.1.16 and os.platform() was added in v0.5.0 (later)
Is os.platform() being deprecated?
EDIT: I would expect process.platform to go at some point, I read it as part of a refactoring / restructuring in the node js api - but I could be wrong

[jamesgeorge007]

@raix There is no harm in having os.platform(). But still, the refactor ensures consistency IMO.

[joaomoreno]

Sure, why not. Thanks! 🍻
