* docs: use hyphen instead of underscore in file name and title/slug
We've been very inconsistent with our use of separators previously
(we should try and find a standard). Hyphens are most common online,
so I've switched to that instead.
* docs: use syntax highlighting for shell commands
* docs: start outlining impression data restructure.
* docs: Add impression data info to API: create toggles
* docs: Add impression data row to compatibility matrix
* docs: restructures the impression data reference doc.
* chore: remove question callout in source material
* docs: add redirect for `impression_data` -> 'impression-data'
* docs: Add sdk availability to availability note
* chore: Fix broken doc paths.

Add a new .../:feature/variants API
This adds
- `GET /api/admin/projects/:projectId/features/:featureName/variants` which returns
```json
{ version: '1', variants: IVariant[] }
```
- `PATCH /api/admin/projects/:projectId/features/:featureName/variants` which accepts a json patch set and updates the feature's variants field and then returns
```json
{ version: '1', variants: IVariant[] }
```
- `PUT /api/admin/projects/:projectId/features/:featureName/variants`
which accepts a IVariant[] and overwrites the current variants list for the feature defined in :featureName and returns
```json
{ version: '1', variants: IVariant[] }
- This also makes sure the total weight of all variants is == 1000
- Validates that there is at least 1 'variable' variant if there are variants
- Validates that 'fix' variants total weight can't exceed 1000
- Adds tests for all these invariants.
