[Bug] typo in src/pages/Presentation/sections/Counters.js

[ZongZheJiang]

At line 48 of Counter.js, the code is as follows

        <Divider orientation="vertical" sx={{ display: { xs: "none", md: "block" }, ml: 0 }} />

when it should be

        <Divider orientation="vertical" sx={{ display: { xs: "none", md: "block" }, mx: 0 }} />
