fix(core): remove extra maybe_with_colon from Solana [no changelog]

This commit removes an extra colon that was being added to Solana transaction confirmation screens on Trezor devices. The change is cosmetic: it stops showing a duplicate colon in front of property names (like 'Fee payer:' becoming 'Fee pa…
