add instructions on requesting a Grant in "Doing Internal Work"

https://docs.dorg.tech/workflows/doing-internal-work

in addition to committed roles, another alternative to the swarm for larger scopes of work should be a grant proposal. we should have some small instructions guiding people on how to request grant funding.

this should also be reflected as a grant template in the forum's Outflows category.

here is an example: https://forum.dorg.tech/t/daoification-mvp/362

阅读 https://docs.dorg.tech/workflows/doing-internal-work 上的“Doing Internal Work”页面，并将其中现有的指南与 https://forum.dorg.tech/t/daoification-mvp/362 上的示例 grant 提案进行比较。向 workflow 文档中添加简明的 grant 请求说明，并在论坛的 Outflows 类别中创建匹配的模板。当这两个位置都说明如何请求 grant 资金并提供一个可用模板时，即视为完成。
