* docs(cache): misc adjustments for Dart
Dart cache adjustments:
- Add guide/index (it was being inherited directly from latest before).
- Add proper cache of `_quickstart_repo.jade` (it used to be just an
include).
Also:
- In `_quickstart_repo.jade` use variable set to URL of repo.
- Fix newly added link to Quickstart in guide/index.jade.
* dart/displaying-data: just use TS's _quickstart_repo
* docs(guide/index): feedback link to Dart repo for Dart
- Also added links to chapters mentioned in table.
- Other minor copyedits.
* docs(api): issue links should refer to Dart repo
* post-review updates
* add link to Advance and Guide chapters
* ensure that we can determine which language is active
* docs: adjust page heading levels
Only the page TOC should be at heading level 1. All other headings
should start at level 2. This commit also removes duplicate headings,
in continuation of #2796.
(This fix is necessary to support an auto-TOC feature.)
- Eliminate use of deprecated `clear=“all”` in `<br>`.
- No need for local `langName`; use global `_Lang` var instead.
- Remove duplicate id `learning-path`.
