Add dependabot cooldown; bump Astro & esbuild

Add a 7-day cooldown to Dependabot update configs to reduce frequent PR noise. Add npm and VS Code Extension links to the website social links. Bump website dependency constraints for astro (to ^5.17.3) and esbuild (to ^0.27.3) and update the lockfile accordingly.
