GP: Site misc changes

[jimaek]

1. og:url should match the page URL and canonical which is missing I believe. e.g. https://globalping.io/network-tools/http-from-wilmington
2. Make sure every page has a unique meta description. Including network testing pages. Currently most are duplicated. PM me for text if needed
3. JS error by Google bot https://share.perfstack.net/2024/10/TabTip_2024-10-05_14-44-02.png
4. Wrong title parsing https://globalping.io/network-tools/http-from-united-states it should United States
5. Add verification file:

With the key as its name: http://globalping.io/cpeg1w6qcnguzr9kjy1c5gt2cft1tx9f.txt
And the key as its content: cpeg1w6qcnguzr9kjy1c5gt2cft1tx9f

Some may be not necessary, its based on Google search, Bing and Ahrefs analysis
