Updated needed to "environment.yml"

[Himscipy]

Hi,

Due to the change in change in the Pip code has changed its behavior to be more strict with respect to file: URI syntax. As pointed out by a PyPA member and Pip developer, the syntax file:requirements.txt is not a valid URI according to the RFC8089 specification.

line 22 in environment.yml need a change
to avoid following error

Pip subprocess error:
ERROR: 404 Client Error: FileNotFoundError for url: file:///requirements.txt

failed

Current: - -r file:requirements.txt

should be changed to

Update: - -r requirements.txt

stack-overflow solution

Thank you
