Update erc1155.adoc

[Vikt0rPavlik]

Description:
This PR includes minor but important fixes to the ERC1155 documentation to improve consistency and professionalism:

1. Changed "multi token standard" to "multi-token standard" to follow proper hyphenation rules for compound modifiers
2. Replaced outdated formal "said contract" with "the contract" in the "Receiving tokens" section for better readability

Files changed:

• docs/modules/ROOT/pages/erc1155.adoc

The changes maintain technical accuracy while improving the documentation's clarity and consistency with modern technical writing standards.
