Update of MAINTAINERS.MD

[larsolofsson]

papiNet needs to keep MAINTAINERS.md updated.

According to GOVERNANCE.md to change maintainers, it requires a pull request with approval from a two-thirds supermajority vote of the current maintainers.
Currently there are 8 voting maintainers. It means that papiNet needs 6 votes to change maintainers.
