Update CD HB to Include HC budget language

Why is this change being made?

This change to the HB updates the acquisition process order of operations to confirm earlier in the process that budget exists to fund acquired headcount. By moving this step to post-product call, rather than during final approvals, we create two forcing functions:

1. Forces the product team to evaluate the deal in relation to all other FY priorities.
2. Allows the product team to determine if headcount can be funded with existing/planned open job requisitions or a reallocation of operating expense.
   1. If the answer is no, budget does not exist, product+finance leadership can debate if the acquisition supersedes other initiatives and should be funded via reallocation or a budget amendment.

In addition to being a forcing function to answer fundamental deal questions, by moving this step forward in the acquisition process we will prevent superfluous work, e.g. cross functional teams work diligently for a month to present a finalized deal case only to find out that budget does not exist to bring on new headcount, sinking the deal and all the efforts that went into crafting the business case.
