fix: handle solc versions with +commit

[grandizzy]

• 8f1c61c introduced an issue with versions like 0.8.15+commit.e14f2714 format that can be seen in foundry CI failure https://github.com/foundry-rs/foundry/actions/runs/19511930077/job/55854689276?pr=12599#step:14:9999
• these versions should be normalized to e.g. 0.8.15
• only prereleases like 0.8.31-pre.1+commit.b59566f6 or 0.8.31-pre.1 should be preserved and looked up with original version
• fix to preserve versions only if prereleases, foundry CI passes with patch: feat: support solc prereleases foundry#12599
• should have created the foundry PR with patched versions to changes first, sorry for back and forth 🫠
