Typo in the variable name on hook_boot() and hook_exit() pages

[findlabnet]

On documentation pages https://docs.backdropcms.org/api/backdrop/core%21modules%21system%21system.api.php/function/hook_boot/1
and
https://docs.backdropcms.org/api/backdrop/core!modules!system!system.api.php/function/hook_exit/1

we have typo: instead 'page_cache_invoke_hook' should be 'page_cache_invoke_hooks' as in bootstrap.inc file, lines 3099 and 3116.

Good catch! Those pages are produced from the actual documentation in the code. So this typo must be fixed in core, in file system.api.php; then it will be fixed on that documentation page. Can you please open an issue in the main backdrop issues queue?

By the way, there is another spot where this is mistyped in core - documentation for hook_exit()

Done. backdrop/backdrop-issues#6273
