Documentation: Create docs on how to contribute to the BPD community

[activus-d]

In how-to/contribute_to_the_bpd_community.md, we need to document various ways community members can contribute to BPD. The created docs should outline different contribution areas such as code, documentation, community support, and event organization.

Any active community member who is familiar with BPD's contribution processes or anyone who is willing to collaborate on our Discord to gather the appropriate information can take on this task.
