* fix broken links, update others to static

original links used dynamic references to the main branch, this updates those to static links for the respective docs eliminating the potential of broken links in the future.

This also fixes other broken links

 While the DID1 specification requires an inner puzzle, there is no set standard on what functionality that puzzle shall entail. Therefore, DID1-compliant inner puzzles with a wide variety of functionality may be used. DID1 will ship with one optional inner puzzle, the details of which are included in this section for your reference.
 
-The reference inner puzzle sits inside the singleton layer and provides the functionality related to being an identity. It is located in GitHub, under [chia-blockchain/blob/main/chia/wallet/puzzles/did_innerpuz.clvm](https://github.com/Chia-Network/chia-blockchain/blob/main/chia/wallet/puzzles/did_innerpuz.clvm).

 DID1 implementations that use the reference inner puzzle must curry the following arguments into its solution:
 * **INNER_PUZZLE:** A standard "pay-to" (p2) puzzle, used to record ownership of the DID
 * **RECOVERY_DID_LIST_HASH:** The hash of the list of DIDs that can be used to recover this DID by sending this DID a message. A hash is stored instead of the full list in order to avoid revealing the whole list every time the singleton is spent
 * **NUM_VERIFICATIONS_REQUIRED:** The number of DIDs from the above list that are required for recovery
 * **SINGLETON_STRUCT:** Defines the singleton used with this DID. Contains the following structure
   * ((SINGLETON_MOD_HASH, (LAUNCHER_ID, LAUNCHER_PUZZLE_HASH))), where:
-    * **SINGLETON_MOD_HASH** is the tree hash of [singleton_top_layer_v1_1.clvm](https://github.com/Chia-Network/chia-blockchain/blob/main/chia/wallet/puzzles/singleton_top_layer_v1_1.clvm) without any curried arguments

     * **LAUNCHER_ID** is the coin_id of the singleton used with this DID
-    * **LAUNCHER_PUZZLE_HASH** is the tree hash of [singleton_launcher.clvm](https://github.com/Chia-Network/chia-blockchain/blob/main/chia/wallet/puzzles/singleton_launcher.clvm), which creates the singleton coin and announcement

 * **METADATA:** A list of customizable key/value pairs, e.g. `"metadata": {"foo": "bar", "something": 5}`. May be used to convey a wide variety of information
