fix(L2): polish (#1988)

* polish

move getINfoLinkByChainId to chain constants

pr review - translations

optimism token list, typo, text color for L1 switch

use <Trans /> instead of t

undo unintentional tokenlist order change

use {'Optimism'} instead of {name}

switch deadline implementation

remove unused TYPE import

switch to generalized CHAIN_INFO instead of L2_INFO so we don't have to check in components

add target chain id param to optimism bridge

fix a minor breakpoint issue

reduce sigfigs for header balance

update network card dropdown text for optimism

remove list code

refactor SupportedChainId

* SupportedL1ChainId | SupportedL2ChainId -> SupportedChainId
