AIP naming

[sakulstra]

currently AIP naming is somewhat arbitrary.
The repo ensures collision free naming as it's just filesystem, so no name can appear twice.
Anyhow it's kind of a pain to ensure reasonable file naming.

My suggestion would be for the merge ci to:
a) read the title from the merged markdown -> rename the file to UPPERCASE_TITLE
b) check via ethers for deployed proposals -> prefix the aip with the proposalId to ID_UPPERCASE_TITLE

In theory we could also do both I guess.
