Use HTML table for overloaded methods to resolve Bikeshed fatal errors

[hoch]

Bikeshed currently fails with fatal errors on method overloads when using the <pre class=argumentdef> syntax (speced/bikeshed#1192).

This replaces the argumentdef blocks for earlier overloads of:

• OfflineAudioContext constructor(contextOptions)
• AudioNode.connect(destinationNode, output, input)
• AudioNode.disconnect(destinationNode)
• AudioNode.disconnect(destinationNode, output)
• AudioNode.disconnect(destinationNode, output, input)

with explicit HTML <table class="data"> definitions. This produces identical output while bypassing Bikeshed's argumentdef overload bug, clearing all fatal errors and allowing clean TR autopublishing.

Also clears expected-errs.txt as the build is now 100% error-free.

Spec Rendering Verification (Live W3C Preview)

The PR branch has been verified against the official W3C Spec Generator service:

• Build Status: 200 OK, x-fatals-count: 0 (clean, 0 fatal errors, 0 lint errors).
• Live HTML Preview: W3C Spec Generator Live Output

Visual & Normative Verification

All 5 overloaded method tables render cleanly with complete argument metadata (previously rendering blank cells on main):

(NOTE: These links take long to load but the existing pr-preview is sort of broken. So...)

• OfflineAudioContext(contextOptions):
  • contextOptions: OfflineAudioContextOptions (Nullable: ✘, Optional: ✘)
• AudioNode.connect(destinationNode, output, input):
  • destinationNode: AudioNode (Nullable: ✘, Optional: ✘)
  • output: unsigned long (Nullable: ✘, Optional: ✔)
  • input: unsigned long (Nullable: ✘, Optional: ✔)
• AudioNode.disconnect(destinationNode):
  • destinationNode: AudioNode (Nullable: ✘, Optional: ✘)
• AudioNode.disconnect(destinationNode, output):
  • destinationNode: AudioNode (Nullable: ✘, Optional: ✘)
  • output: unsigned long (Nullable: ✘, Optional: ✘)
• AudioNode.disconnect(destinationNode, output, input):
  • destinationNode: AudioNode (Nullable: ✘, Optional: ✘)
  • output: unsigned long (Nullable: ✘, Optional: ✘)
  • input: unsigned long (Nullable: ✘, Optional: ✘)

Some Notes for Reviewers

1. Zero Regression: Table structure, classes (data), captions, styles, and dfn slide-out panels match Bikeshed's native output.
2. Fixes Blank Cells on main: Due to upstream bug speced/bikeshed#1192, main previously omitted types and optionality flags (emitting empty <td> cells) on all earlier overloads. This PR restores those missing fields.
3. Cross-Links Intact: All WebIDL types, parameters, and exception definitions (InvalidAccessError, IndexSizeError) link correctly.
