Bump version to 4.1.8 - Githubissues

Resolves #22

Motivation

Bumps Blockscout version to 4.1.8

Updates dependencies, Blockscout version, applied original UI changes

[ ] I added an entry to CHANGELOG.md with this PR
[ ] If I added new functionality, I added tests covering it.
[ ] If I fixed a bug, I added a regression test to prevent the bug from silently reappearing again.
[ ] I checked whether I should update the docs and did so by submitting a PR to https://github.com/blockscout/docs
[ ] If I added/changed/removed ENV var, I submitted a PR to https://github.com/blockscout/docs to update the list of env vars at https://github.com/blockscout/docs/blob/master/for-developers/information-and-settings/env-variables.md and I updated the version to master in the Version column. Changes will be reflected in this table: https://docs.blockscout.com/for-developers/information-and-settings/env-variables.
[ ] If I add new indices into DB, I checked, that they are not redundant with PGHero or other tools
