Update changelog for upcoming 0.25.2

[nkrkv]

• [ide] Do not hide any output from the compiler and uploader in the deployment pane. (Make verbose output for compile/upload arduino-cli commands #1490, Fix truncating of the compile & upload log #1502)
• [ide] Fix regression: bring back the message on a successful upload. (Show snackbar message on successful upload #1491)
• [ide] Fix ugly hover color of message and header buttons. (Fix hover and disabled button styles #1492)
• [ide] Fix the scroll position when Deployment pane is opened for the first time. (Fix log position of compile/upload tabs on first show #1494)
• [nodes] Fix clock hang if the EN pin is constantly updated. (Make xod/core/clock tick even if EN is always dirty #1496)
• [ide] Gracefully shutdown long background processes like package installing when quitting XOD IDE. (Fix exception on close of IDE #1500, Kill running arduino-cli processes on closing the IDE #1523)
• [ide] Ensure Edit → Select All and its keyboard shortcut work properly on all OS’es and browsers. (Select all patch entities or input contents from menu item #1505)
• [ide] Do not raise DTR when opening a serial port on Windows. It caused issues with some boards using the CP2102 USB-to-Serial chip. (Don't raise DTR when opening serialport on windows #1507)
• [c++] Make port values validation softer on platforms which violate assumptions about underlying values of A0, A1, number of digital pins, etc. (Fix port validation false negatives #1508)
• [core] Allow literals like PA13, PC8 to be used for port values. It makes XOD usable on STM32-based boards. (Make sure generated C++ is compatible with STM32 boards #1512)
• [ide] Show sensible messages and recover after trying to update package indexes pointed by malformed URLs in extra.txt or when the network is down. (Handle package indexes update fails #1509, Fix joining urls in extra.txt with os-specific EOL instead of \n #1525)
• [ide] Fix helpbox outputs listed in the reverse order for some nodes. (Outputs are reversed in helpboxes sometimes #1432)
• [ide] Always upload to a board with the option set shown in the upload dialog: do not mess option values between different board models. (Compile/upload with correct board options #1519)
• [ide] Fix converting links to buses when they are going toward variadic pins. (Create buses from links leading to variadic pins #1520)
• [ide] Fix offset hotkey label position in the main menu of browser XOD IDE. (Fixes hotkey label position in the main menu #1521)
• [ide] Add missing labels for variadic pins in Inspector. (Add missing labels for variadic pins in Inspector #1522)
• [nodes] Make shift-left and shift-right interpret its inputs as 32-bit integers, fix pin labels and descriptions. (xod/bits/shift-* works with int32_t #1524)
