Make Strict Mode Strict Again (#1938)

* fix: don't format "unorthodox" query input types

Also add support for tuples in `getSimilarTypes`

* fix: refactor type ignore logic into `formatType`

Had to use a regexp solution because types like `([AccountId | string | Uint8Array, Data | { none: any } | { raw: any } | { blakeTwo256: any } | { sha256: any } | { keccak256: any } | { shaThree256: any } | string | Uint8Array])[]` were not being ignored with the current logic, so they were passed to `getTypeDef` and causing delimiter errors.

* refactor: remove superfluous "FirstKeyType" param

* fix: ignore tuples with structs when formatting

* feat: eliminate all index signatures with --strict

* docs: fix doc generation
