fix: advisory_council should default to false

[lwasser]

This is a small fix to ensure that emeritus advisory and advisory roles:

1. default to false
2. always have a bool value which should default to false
3. should not be changed by the code if the value in the data is true (i think this was just a tiny bug that i found).

@lwasser It looks like this field is causing an issue with CI. What is the purpose of always?

[lwasser]

oh shoot @willingc i merged this too quickly. in the PR the tests had passed (well i thought they had maybe they hadn't!) I suspect always=true was made up by LLMS. i often use chatgpt to proof my code / format etc. and it suggested that addition and i used it without researching. this is my mistake. i should know better than to listen to a llm!

[lwasser]

i looked more closely. one had failed. i missed it. - https://github.com/pyOpenSci/pyosMeta/actions/runs/10201975001/job/28225084163#step:5:28 i'll submit a fix and won't be so rushed this time.

Cool! No problem.
