[FL-3317] fbt: allow strings for fap_version field in app manifests

documentation/AppManifests.md

@@ -47,7 +47,7 @@ Only two parameters are mandatory: **_appid_** and **_apptype_**. Others are opt
 The following parameters are used only for [FAPs](./AppsOnSDCard.md):
 
 - **sources**: list of strings, file name masks used for gathering sources within the app folder. The default value of `["*.c*"]` includes C and C++ source files. Applications cannot use the `"lib"` folder for their own source code, as it is reserved for **fap_private_libs**.
-- **fap_version**: tuple, 2 numbers in the form of (x,y): application version to be embedded within .fap file. The default value is (0,1), meaning version "0.1".
+- **fap_version**: string, application version. The default value is "0.1". You can also use a tuple of 2 numbers in the form of (x,y) to specify the version. It is also possible to add more dot-separated parts to the version, like patch number, but only major and minor version numbers are stored in the built .fap.
 - **fap_icon**: name of a `.png` file, 1-bit color depth, 10x10px, to be embedded within `.fap` file.
 - **fap_libs**: list of extra libraries to link the application against. Provides access to extra functions that are not exported as a part of main firmware at the expense of increased `.fap` file size and RAM consumption.
 - **fap_category**: string, may be empty. App subcategory, also determines the path of the FAP within the apps folder in the file system.
