Solana swaps have very high rate of being dropped

[onyb]

Description

The priority fee we use for Solana swaps, which is computed by Jupiter API, is not sufficient to land them with a high success rate. Bump it up based on the updated docs: https://station.jup.ag/docs/apis/landing-transactions#an-example-of-how-jupiter-estimates-priority-fees

Steps to reproduce

Perform a Solana swap and approve it.

Actual result

Transaction ends up being dropped almost all the time.

Expected result

Transaction should be successfully confirmed.

Removing Android and iOS label as the change is on core. Confirmed with @onyb desktop verification is enough

@srirambv I re-added the labels as the above is release-notes/include which means it will most likely be missed for iOS & Android when creating release notes. In these cases, lets just leave the labels but add a comment similar to what you did above re: only needed a single verification rather than checking multiple platforms.
