ogc-api-records running commands in the documentation

[fgravin]

Try to improve the documentation on how to run ogc-api-records microservice

• Main README was refering to a depracted profile local instead of standalone.
• Also add a link to dedicated service README as it's not obvious from the root that they exist.
• Make ogc-record-api README more straightforward to read
