fix: issue-1758: fixed broken anchor links in docs

[parminder0907]

Issue #1758

Fix broken sidebar links for Consuming Messages page.

What

Fixes sidebar navigation for headings (e.g. fromBeginning).

Issue

Sidebar links point to incorrect anchor names in Consuming.md markdown:

Sidebar: fromBeginning
Anchor name: #from-beginning ❌
Anchor name: #frombeginning ✅

Sidebar: Partition-aware concurrency
Anchor name: #concurrent-processing ❌
Anchor name: #partition-aware-concurrency ✅

This causes broken navigation when clicking sidebar items.

Fix

Align sidebar links with the actual anchor name.

Result

Sidebar links now navigate correctly
Consistent behavior across all headings

Notes

Tested locally on the docs site; navigation works as expected.
