fix: correct broken links, typos, and grammar in Generic Extractor docs (PRDCT-365 audit)

[Iamfle4ka]

Jira issue(s): PRDCT-365

Changes:

Unambiguous fixes from the PRDCT-365 developers-docs audit of /extend/generic-extractor/. All 3 needs_human items (A4: backoff formula, A5: retryConfig sample, A6: zendesk.response.url) are excluded — zero needs_human rows in this diff.

Code-accuracy fixes (Block A):

• A1 pagination/index.md: Fix broken link — offset methods pointed to .../pagination/pagenum/ instead of .../pagination/offset/
• A2 pagination/index.md: Remove stray ] after [EX139] markdown link
• A3 pagination/index.md: Fix nextFlag → nextPageFlag (matches HasMoreScrollerDecorator.php:39)

Doc-hygiene fixes (Block C):

• C1 ssh-proxy/index.md: Typo "tu" → "to"
• C2 ssh-proxy/index.md: Fix sentence fragment between EX131/EX133 links
• C3 aws-signature/index.md: "signaturing" → "signing"
• C4 aws-signature/index.md: "extractor sign" → "the extractor signs"
• C5 config/index.md: Merge broken sentence fragment in userData docs
• C6 pagination/index.md: Clarify mutually exclusive limitStop params (count/field)

Verdict: needs_human (risk 2/5) · profile docs

Clean, low-risk docs fixes, but a link target and two product-behaviour claims can't be verified from the diff — route to human.

Concerns:

• extend/generic-extractor/configuration/api/pagination/index.md: A1 new link target .../pagination/offset/ existence unverifiable at HEAD
• extend/generic-extractor/configuration/api/pagination/index.md: A3 param rename nextFlag→nextPageFlag is a product-behaviour claim; confirm
• extend/generic-extractor/configuration/api/pagination/index.md: C6 limitStop count/field requirement change needs product confirmation

Superseded by #410, which carries all four files. One hunk was dropped as a duplicate — the pagenum → offset link, which #402 fixes identically. Open 43 days with no human review.

All three of the bot's concerns are now confirmed:

• .../pagination/offset/ exists — that hunk rides on PRDCT-480: fix broken links, dead anchors, invalid JSON examples, and typos across the docs #402 rather than here, and the target page is real.
• nextFlag → nextPageFlag. Code search over keboola/generic-extractor: nextPageFlag appears 5 times (README plus the configs of examples 045, 046, 047 and 139); nextFlag appears 0 times. The documented name was never a valid option.
• limitStop's count / field are conditionally required. The list marked both "(required)" while the next sentence called them mutually exclusive with one required — the page contradicted itself. Upstream settles it: doc/examples/126-pagination-stop-limit/config.json sets {"field": "scroller.count"} alone and 127-pagination-stop-field/config.json sets {"count": 3} alone.

Generic Extractor stays on this site (per DEV-MIGRATION-PLAN.md), so unlike #393 and #396 this PR's content belongs here — it just needed rebasing and deduplicating against #402.

Branch stays cherry-pickable.
