[CHICKEN 6] SRFIs for C5/C6

Hey all,

I'd like to update the release-info URLs (if necessary) for CHICKEN 5; 
similarly, these eggs can all be added to C6 as well:

- SRFI-128 <https://gitlab.com/ThatGeoGuy/srfi-128/-/raw/main/srfi-128.egg>
- SRFI-133 
<https://gitlab.com/ThatGeoGuy/srfi-133/-/raw/main/srfi-133.release-info>

Additionally, I think the following eggs should likewise work once 
SRFI-128 is included into the coop.

- SRFI-113 
<https://gitlab.com/ThatGeoGuy/srfi-113/-/raw/main/srfi-113.release-info>
- SRFI-116 
<https://gitlab.com/ThatGeoGuy/srfi-116/-/raw/main/srfi-116.release-info>

Cheers,
