ci: fix syntax error in workflow_dispatch

[abhidg]

workflow_dispatch does not take paths or branches

Is the resulting YAML valid? It looks like declaring a key without a value.
If not, we should be able to use {}.

Out of curiosity, where did you find that workflow_dispatch does not take paths or branches? I can't find it in the Github documentation, and I do see one post about it that links to code that has branches removed in a later commit.

delete just this block and leave the above config intact?

[abhidg]

typo! thanks

GitHub Actions seems to be fine with it, as is pyyaml (yaml.safe_load("a:\n b:\n c:\n")), which keeps the value at None.
