Python and the community's mission. No structural changes made to the

Refactor/landing page

Refactored the landing page view to provide board members as a static list
instead of querying the Volunteer model. Also renamed 'commitees' to
'committees' for consistency and updated the template context accordingly.
This improves maintainability and fixes template variable mismatches.

Refactor: Update board and committee context

Updated the our_team.html template to use the correct 'committees'
variable instead of the misspelled 'commitees'. This ensures committee
data is displayed properly and aligns with the updated view context.

Fix: Correct template variable for committees
