fix: correct Node.js version prerequisite to >= 20.0.0

[dorukardahan]

Summary

• Fixed Node.js version prerequisite from >= 22.0.0 to >= 20.0.0 in two compute network docs pages

Why

The SDK's package.json engines field specifies >=20.0.0, and this was already corrected in the SDK README via PR #172. The docs pages still had the old 22.0.0 requirement, which could cause confusion for developers using Node.js 20.x or 21.x.

Files changed

File	Change
docs/.../compute-network/inference.md	Line 16: 22.0.0 → 20.0.0
docs/.../compute-network/account-management.md	Line 44: 22.0.0 → 20.0.0

Verification

• Confirmed against SDK package.json (>=20.0.0) and merged PR feat: enhance SDK documentation with CLI quick start and improved str… #172 README fix
• Searched all docs for remaining 22.0.0 references — none found

Self-review: improvements from a second pass

Verification note: The official llms-full.txt at docs.0g.ai also says Node.js >= 22.0.0 — this PR fixes the source markdown files that generate that output. The SDK's package.json has "node": ">=20.0.0" which is the authoritative source for the actual Node.js requirement.

Scope check: Searched all docs for remaining 22.0.0 references after this PR — none found in the compute network section. The llms-full.txt will update automatically when the docs rebuild.

Cross-reference: This is consistent with PR #172 on 0g-serving-user-broker (already merged) which fixed the same 22→20 version in the SDK README.

@Ravenyjh Quick question: The SDK package.json specifies "node": ">=20.0.0" and the README (fixed in PR #172) now says >= 20.0.0. But I noticed the docs have been at >= 22.0.0 for a while — is this intentional (e.g., CLI tools or other dependencies need Node 22)? Or should docs match the SDK at 20.0.0?

Happy to revert if 22.0.0 is the intended minimum.

Version >20.0.0 is ok. The additional dependencies that previously required version 22 or higher are no longer present
