refactor(@angular-devkit/build-angular): update browserslist conversion to latest esbuild browsers

Browse Source 
The conversion of browserslist targets to esbuild targets has been updated to reflect additions
to esbuild. Additional browsers are now supported and the major/minor versions have been normalized.
The later of which ensures that `.0` major versions are not misinterpreted as ranges rather than
specific versions.
