W-10330211 Removing isotope dependency (#86)

* Removing isotope dependency

The following layouts no longer exclude the `IsotopeSubscription` button
to remove the dependency on Isotope being enabled for the org:
- `outfunds__Disbursement__c-OFM Disbursement Site Layout.layout-meta.xml`
- `outfunds__Funding_Program__c-OFM Funding Program Site Layout.layout-meta.xml`
- `outfunds__Funding_Request__c-OFM Funding Request Site Layout.layout-meta.xml`
- `outfunds__Requirement__c-OFM Requirement Site Layout.layout-meta.xml`

* un-excluding Funding Request ChangeRecordType

For the OFM Funding Request Site Layout, modification of the Funding Request in the Community UI is allowed, so I un-excluded the `ChangeRecordType` button.

However, I don't think we should un-exclude `ChangeRecordType` for the following layouts since the `Edit` button is excluded implying the object records should not be modifiable in the Community UI:
- OFM Disbursement Site Layout
- OFM Funding Program Site Layout
- OFM Requirement Site Layout
