[BUG] flit_core not being mapped correctly to flit-core

[dhirschfeld]

When using the generator in the Prefix discord channel grayskull creates a recipe for sqlmermaid with the below requirements:

requirements:
  host:
    - python >=3.8
    - flit_core >=3.2,<4
    - pip
  run:
    - python >=3.8
    - sqlalchemy >=2.0.0

sqlmermaid does indeed depend on flit_core:
https://github.com/endremborza/sqlmermaid/blob/aed1925d5455e26049f61a9905488145635bfea7/pyproject.toml#L21

...but on conda-forge the package is called flit-core
