data(algorand): add official BetaNet faucet

[bountyforge-lab]

Summary

Add the active, official Algorand BetaNet dispenser as a canonical faucet offer and network listing.

• record the official BetaNet faucet and documentation links;
• record its verified access requirements: no login, reCAPTCHA, and zero cost;
• note that dispensed ALGOs have no monetary value and are only for application testing;
• add the required betanet.png chain asset by reusing the existing Algorand network artwork.

Type of change

• Add data rows
• Update data rows
• Remove data rows
• Schema change
• Documentation/metadata only

Scope

• Network affected: Algorand

• Live BetaNet dispenser: https://bank.betanet.algodev.network/

Validation

• Read and followed the Style Guide and Faucets column definitions.
• Personally verified the official documentation and live faucet endpoint.
• Confirmed the live page returns HTTP 200, embeds Google reCAPTCHA, and does not require login.
• Confirmed no open PR contains betanet or the dispenser URL before submission.
• Kept both CSV files A-Z sorted and used canonical !offer: syntax.

Verdict: APPROVE
Risk: LOW
Summary: The BetaNet faucet addition is structurally consistent with the Algorand faucets data. The listing uses a resolving canonical !offer:algorand-betanet-dispenser-algo reference, both touched CSVs keep stable column widths with unique slugs, git diff --check is clean, and the new betanet.png chain asset is a 300x300 RGBA PNG with transparent corners matching the existing Algorand chain artwork. Algorand's own network reference lists BetaNet and the BetaNet faucet URL, the live dispenser returns HTTP 200 and uses reCAPTCHA, required validation is passing, and the current review-cycle link-check succeeded with 2/2 links successful and 0 errors/timeouts/unsupported.
Findings: None.
Confidence: HIGH
