A small fix for two problems introduced #8669.
* Two tab should be used to indent instead of four spaces in
`tiddlywiki.info` in full edition.
* Changed description for `en-PH`. Since "PH" isn't a country name like
"US", it should be "Philippines".
* initial en-PH
* English (PH) [en-ph] translation v1
* fix: moved en-PH to the correct file in /editions/full/tiddlywiki.info
* deleted since changes were mainly on styles, like em or en dash instead of regular dash
* upd: 'dependents' not needed in this particular case
* deleted 'empty' files
* upd: removed modifications which were mainly related on style (like em and en dashes);
upd: CamelCase instead of separating camelCase and PascalCase (see https://github.com/TiddlyWiki/TiddlyWiki5/pull/8669#pullrequestreview-2352481385 )
* upd: Simplified Confirm* strings;
upd: natural DateFormat (instead of formal format)
* upd: 'want' instead of 'wish'
* upd: natural DateFormat (instead of ISO format)
* minor: used 'the' instead of 'a' or 'an' as reading of '.html' depends on the reader (ie. a 'dot html' extension vs an 'html' extension)
