change copies from commit to buy

[albertfolch-redeemeum]

1. Toast notification that is shown after committing, it says Commit to offer: ${offer.metadata?.name || ""}

2. Copy shown in void modal {offers && offers.length ? "By voiding these items, it will no longer be possible for buyers to commit to these products however any existing exchanges will be unaffected." : "By voiding this item, it will no longer be possible for buyers to commit to this product however any existing exchanges will be unaffected."}

3. While setting the core terms of sale in the creation of a product: infiniteExpirationOffers ? "The offer start date is the date from when buyers can commit to your offer." : "The offer validity period is the time in which buyers can commit to your offer."

4. Redemption duration subtitle: The redemption duration is the number of days a buyer has to redeem the rNFT for the physical item, from the later of the commit date or the redemption start date.

5. Help section: All offers must specify a start date, or the date from when buyers can commit to your offer. You can choose to either set a specific end date, or default to no specific end date.

6. Help section: If I set my offers without a specific end date now, can I change it in the future so that buyers will no longer be able to commit to it?

7. Help section: Yes. You can 'Void' an offer in the Seller Hub so that buyers will no longer be able to commit to the offer.

8. Help section: When your offer validity period ends, buyers will no longer be able to commit to the offer.

9. In transaction history modal: "Commit" : "Committed"

10. Error message in your own buyer page if you dont have any exchanges (I think this text is wrong here anyway): Commit to some products to see your chat conversations

11. In chat: Commit to some products to see your chat conversations (same as above but here it does make sense)

12. In dapp terms and conditions (it shouldnt be changed I think): commit any violation of applicable laws, rules or regulations;

13. In dr center terms and conditions (it shouldnt be changed I think): commit any violation of applicable laws, rules or regulations;

14. public buyer profile (I think this is wrong too): Commit to some products to see your chat conversations

15. buyer/exchanges: There are no exchanges yet, commit to at least one product first

16. seller/exchanges: There are no exchanges yet, commit to at least one product first
