Set permissions: write-all in hosting.md

[rikhuijzer]

GitHub seems to have changed the permissions for the secrets.GITHUB_TOKEN. It does not allow writing by default anymore. I've now had two new repositories where I copy-pasted some workflow and got the following back

Explicitly setting

permissions: write-all

fixed it.

More information about the permissions for the GITHUB_TOKEN can be found at https://docs.github.com/en/actions/security-guides/automatic-token-authentication. I haven't yet found related release notes.

Yep, can confirm that it looks like new repositories are created with read-only permission on GITHUB_TOKEN by default now:

So this LGTM. Thanks @rikhuijzer!
