[LDN v3 flow] Check The "V3 Multisig Address" to top it up

[fabriziogianni7]

Add a functionality to track the datacap allocated to the "V3 mutisig address"

• When datacap < 25% of total granted (25PiB) ---> trigger new allocation request of 25PiB
• The bot should post the reuquest in the corresponding notary-governance issue

steps:

• add an env var with the ldn v3 issue number (we can use a manually created one)
• add an env var with the ldn v3 multisig address (we can use a manually created one)
• add a script to check the remaining datacap for the adress, just like this -->
